I try the following :

Run xamp control panel as admin => no success
remove temporary table ibdata1 and ibtmp1 => no success
If someone have an idea...
EDIT : I try to install as a windows service via admin panel as administrator. And so, i have some new lines in log. Seems user table is corrupted... how can i repair ?

This one helped for me:
Open shell from from control panel and start mysql with this command:
mysqld –-console –-skip-grant-tables –-skip-external-locking
Open another shell from control panel and repair database with this command:
mysqlcheck -r --databases mysql --use-frm
Stop mysql, close shells and restart mysql normally.
based on: Re: Corrupt mysql.users How to fix
I got this problem like you . I have solved this problem like below.
Copy from xampp/mysql/backup folder and paste in xampp/mysql/data folder except ibdata1 file.
If you replace ibdata1 file from xampp/mysql/data then some database you will get error table does not exist.
This one helped for me:
Open shell from from control panel and start mysql with this command:
mysqld –-console –-skip-grant-tables –-skip-external-locking
Open another shell from control panel and repair database with this command:
mysqlcheck -r --databases mysql --use-frm

Hello!
Just do these simple steps:
Rename the folder C:\xampp\mysql\data to C:\xampp\mysql\data_old
(or any name)
Create new folder C:\xampp\mysql\data
Copy the content that is inside C:\xampp\mysql\backup to
C:\xampp\mysql\data folder
Copy all your database folders that are in C:\xampp\mysql\data_old to
C:\xampp\mysql\data (skip performance_schema, mysql and
phpmyadmin folders from C:\xampp\mysql\data_old)
Finally copy the ibdata1 file from C:\xampp\mysql\data_old and
replace it inside C:\xampp\mysql\data folder
Now Restart MySQL from XAMPP control panel.
And I am sure its all done...
I had the same problem today and i fixed it by deleting all master-xx.info files and the multi-master.info file in C:\xampp\mysql\data
After I started it again it made a new and empty multi-master.info file and it worked perfectly fine again. No Data was lost
I'm using XAMPP for Windows and MySql was working fine for the longest time, but now (after a Windows update I think) it crashes on start-up. When I click on "Start" in the Control Panel, I get a short flash of the PID and Port 3306 before it shuts down again.
This is the error I get in XAMPP:
09:14:09 [mysql] Error: MySQL shutdown unexpectedly.
09:14:09 [mysql] This may be due to a blocked port, missing dependencies,
09:14:09 [mysql] improper privileges, a crash, or a shutdown by another method.

I have already checked the port (3306): Nothing is blocking it. I have no other instances of MySQL running on my computer. Neither in the Task-Manager nor in the services.msc. But just to be sure I changed the port for MySql to 3308, but it still wouldn't start.
I also tried deleting ibdata1, ib_logfile0,ib_logfile1,ib_logfile101 in xampp/mysql/data.
The last thing I tried was setting up IPv6 which I know was a hail mary.
Any help would be appreciated.
I solved it by doing this:
https://stackoverflow.com/a/11013868/11824001
And then following the error messages I was getting in PhPMyAdmin.
Turns out my mysql.db table was corrupted and had to be repaired with:
use mysql
repair table db;
This message is in my XAMPP control panel when I click the start button.
This warning is showing that MySQL shutdown unexpectedly, but the Apache Server is running fine.

I tried most of the things I found on StackOverflow, but it didn't work.
Can anyone help me to find a solution?
I found this helpful after searching for nearly an hour online.
You can go through the solution screenshotted here or browse the XAMPP forum here
This method solved solved my issues
Step 1. Rename the folder c:\xampp\mysql\data to c:\xampp\mysql\data_old (you can use any name).
Step 2. Create a new folder c:\xampp\mysql/data.
Step 3. Copy the content that resides in mysql\backup to the new mysql\data folder.
Step 4. Copy all your database folders that are in mysql\data_old to mysql\data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old).
Step 5. Finally copy the ibdata1 file from mysql\data_old and replace it inside mysql\data folder.
Step 6. Start MySQL from XAMPP control panel.
And, Its DONE . No databases lost, no ports changed, no run as administrator, no force recovery, no kill mysqld process, no restoring from previous versions, no more errors.
For more information check this blog post
Main issue that I faced is, some of my database size is to high.
But ibdata1 can not be auto extended.
So I did those step and my error was fixed.
Go to mysql/data folder
remove aria_log.00000001, aria_log_control, ib_logfile0, ib_logfile1, ibdata1, mysql.pid
Go to the my.ini from mysql/bin
Here you will find some buffer size related key values like->
key_buffer, max_allowed_packet, sort_buffer_size, net_buffer_length, read_buffer_size, read_rnd_buffer_size, myisam_sort_buffer_size, innodb_data_file_path, innodb_buffer_pool_size, innodb_log_file_size, innodb_log_buffer_size, innodb_lock_wait_timeout, max_allowed_packet
restart apache and mysql
check if it is solved or not.
100% worked for me.
The MySQL service will no longer start on my XAMPP installation on a Windows 10 machine. The error message in the XAMPP console says:
Error: MySQL shutdown unexpectedly.
This may be due to a blocked port, missing dependencies, improper privileges, a crash, or a shutdown by another method.
The error log shows this:

Aborting
When an attempt is made to connect to MySQL, it doesn't work (which makes sense because the MySQL service will not run). This is the error message given in CMD after an attempt is made to connect: ERROR 2002 (HY000): Can't connect to MySQL server on 'localhost' (10061).
Posts related to MySQL tables that need to be repaired require connecting to MySQL so they do not help in this situation. If it's possible to repair mysql.db on a Windows 10 machine without connecting to MySQL, what are the steps to do so?
This one helped for me:
Open shell from from control panel and start mysql with this command:
mysqld –-console –-skip-grant-tables –-skip-external-locking
Open another shell from control panel and repair database with this command:
mysqlcheck -r --databases mysql --use-frm
Stop mysql, close shells and restart mysql normally.
