I've tried many things said on the internet, also tried to fix it myself, but I don't have any clue, what I could do next. I can't Reinstall it, because there is important data on it.

I've tried updateing the config.
I've tried booting without password.
There are currently two methods:
Modify the value of innodb_force_recovery in the parameter file, and then start the database. If it succeeds, you need to export the data, then recreate the database, and then import the data. If not, refer to the second point.
There are some tools, some paid and some free. You can retrieve the data through the ibdata file, and rebuild the database after retrieval.
Of course it is very important not to delete the data files

my Xampp MySql won't start. Elsewhere in this forum was has been advised to change the file name C:\xampp\mysql\data\ibdata1 to ibdata1.bak and turn off the Xampp. But it did not help. Is there a way to fix this?

check your PC time and sync it with real time!
remove all files which have a date-time more than your PC date-time (if possible! if not, create a new one in a proper date). For example your PC date is 2019-xx-xx and your files is 2020-xx-xx.

I get following error in windows events
The description for Event ID 100 from source MySQL cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Slave I/O: Unable to load replication GTID slave state from mysql.gtid_slave_pos: Table 'mysql.gtid_slave_pos' doesn't exist in engine, Internal MariaDB error code: 1932
A simple and effective solution is:
To copy your database files ibdata1 and database folders from c:\xamp\mysql\data to a safe place as backup
Copy all your website files from c:\xamp\htdocs to a safe place as backup
Head to applications (MAC) or control panel (Windows) and uninstall the current xampp version
Download the latest xampp version and install.
Copy back your files to their respective places
Done.
Your applications should be back normal and working fine. I hope it helps someone.
If you want a faster & easier way of fixing this problem, instead of re-installing XAMPP & reconfiguring everything, then look in your /xampp/mysql/data/ folder for any files, which have these prefixes & really long file names. They will almost all have a plethora of repeating "#" symbols in their file names, like so:
master-...#...#...#..#...
multi-...#...#...#..#...
mysql-relay-bin-...#...#...#..#...
relay-log-...#...#...#..#...
If you find those files - which are not standard short table names, but rather crash dump files - then make a /backup folder & simply move them into that folder. Then you can restart MySQL through the XAMPP control panel, without it failing. That's an easy & fast fix, which I just discovered & used to solve the same problem!
Addendum: 7-24-2022
If MySQL fails to startup after deleting those files, then delete this file too:
multi-master.info
Then MySQL should startup, plus remain up & running in XAMPP.
MySql stops unexpectedly

What can I do to get my database up and running again?
All help is greatly appreciated!
I have faced the same problem. I just followed the below steps
Step 1: Moved(cut/paste) all the files in C:\xampp\mysql\data to desired backup location.
Step 2: After that copied all the files from C:\xampp\mysql\backup to C:\xampp\mysql\data
Step 3: Restarted mysql and checked the phpmyadmin url, it worked.
Step 4: After that stopped mysql and copied ibdata1 file from backup location to C:\xampp\mysql\data
Step 5: Restarted mysql
Step 6: After that copied all database folders and checked all the tables, It worked.
I also faced this issue and searched a lot only one solution worked for me.
Just copy all files from C:\xampp\mysql\backup to C:\xampp\mysql\data
Make sure to take backup of your data folder to avoid any further problems.
If you see any error related to table engine then you can copy file ibdata1 from your backup data folder to current data folder
Seems that there is corruption in MySQL log and/or data files, one way to workaround this problem is to start MySQL in recovery mode.
From my.ini in windows (or my.cnf in Linux) add the following line:
innodb_force_recovery=1 under [mysqld] section then re-start MySQL service.
If the problem persisted, mysqlcheck can help, move to the folder where MySQL binaries exist in your machine, and in Command Line execute ./mysqlcheck.exe --all-databases this will list tables that are corrupted
Reference:
https://dev.mysql.com/doc/refman/8.0/en/forcing-innodb-recovery.html
Just Unintall XAMPP and the reinstall it , it will resolve all the issue , but make sure to have the backup of your MYSQL database.
If your backup folder doesn't include your latest DB changes and you are stuck with collation of in use, then do this instead:
Install another XAMPP instance in new folder;
Copy the single folder of: [old_xampp]/mysql/data/[table_name]/ into [new_xampp]/mysql/data/;
Copy a file from: [old_xampp]/mysql/data/ibdata1 to: [new_xampp]/mysql/data/ibdata1 and replace it;
Stop old XAMPP;
Run new XAMPP.
DONE!
All your new table entries should be brought back.
I'm developing locally and using Mamp Pro.
Basically MySQL is having trouble starting and here's the error message from the error log:
Any idea how to resolve this?

Recently encountered similar issue developing locally w/ MAMP. Log included "Database was not shutdown normally", similar error messages after that point, and the suggestions as well. Below are steps that resolved it:
Stop servers in MAMP
Navigate to the .idb files for your WP DB - if using MAMP, should be somewhere like ~/Library/Application Support/appsolute/MAMP PRO/db/mysql56/[yourdbname]/
Add .bk (or any unrecognizable extension) to the end of the .idb filenames
Start servers in MAMP. If you view logs, you'll see a bunch of error messages related to not finding the .idb files, but at least MySQL should start.
Stop servers in MAMP
Drop the .bk (or whatever you used) from the .idb file names
Start servers in MAMP - at this point, should be all set.
Hadn't yet done much work with the DB, so was willing to lose data or even reinstall MAMP; if your situation is different, probably best to first backup your db directory to a .zip file so you can try something else later if no luck.
Hope this helps.
....
UPDATE:
Have found it faster to replace steps 3 and 6 with the following:
3. Create a temporary folder somewhere handy; select all the .idb files and move them into that folder.
6. Move the files back into the original folder from Step 2.
....

plz somebody help , i have one important database ,whose backup i have not made , i posted this question earlier ,but didnt got the answer ...this started when i was trying to access phpmyadmin , from then on mysql is not starting.
I see two potential ways out of it.
For the following:
Table '.\mysql\db' is marked as crashed and last (automatic?) repair failed
You can use mysqlcheck to repair it, if it is a MyISAM DB. Else try the InnoDB force recovery option if it is InnoDB database. You can start your DB with InnoDB force recovery and take a DB dump from it, to restore it on a fresh MySQL install.
In future, try enabling innodb_file_per_table option.
Now, second option. Even though the first one looks most likely.
The log sequence numbers 1665244 and 1665244 in ibdata files do not match the log sequence number 15857945 in the ib_logfiles!
If the first method doesnt work, give this a try. It looks like the ib_logfiles are corrupt, I faced this issue before and used the following steps to get my DB up and working:
Take a full backup of your mysql datadir in another directory.
Make sure mysql service is stopped.
remove the ib_logfile1 and ib_logfile2
Start the MySQL service
Hope it helps
Rishav, innodb_force_recovery doesn't recover anything. It is a mode you start your mysql with. Once it starts, you should be able to take a dump. Following should be the steps:
Steps to get it back up.
1. Stop mysqld.
2. Backup /var/lib/mysql/ib*
3. Add the following line into /etc/my.cnf
innodb_force_recovery = 4
4. Restart mysqld.
5. Dump your DB using mysqldump to a dump.sql file.
6. Drop all databases which need recovery.
7. Stop mysqld.
8. Remove /var/lib/mysql/ib*
9. Comment out innodb_force_recovery in /etc/my.cnf
10. Restart mysqld. Look at mysql error log. By default it should be /var/lib/mysql/server/hostname.com.err to see how it creates new ib* files. (Although, I recommend a fresh setup here)
11. Restore databases from the dump:mysql < dump.sql
