Windows / MySQL 5.5. / Crash on startup on exeption 0xc0000005 - mysql

Question

i have Windows 2016 Standard OS with installed MySQL 5.5.33.0.
This morning I found out that the mysql server is not running and cannot be turned on. When i try to turn it on, it crashes immediately, and there is only exception information 0xc0000005 in Event Viewer. I can't even run mysqlcheck because it doesn't work when mysqld isn't running.
I will be very grateful for any advice.
I was able to enable logging and set paths in MySQL settings. There are quite a few entries in the log with this text (numbers change):
210107 10:28:21 InnoDB: Error: page 33382 log sequence number 114951961648
InnoDB: is in the future! Current system log sequence number 111386529682.
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files.
See InnoDB: dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html
InnoDB: for more information.

InnoDB: that table.

Progress update:
I managed to start MySQL with innodb_force_recovery = 3 and it even runs for a while. If I run mysqlcheck.exe --all-databases --auto-repair, it reports corrupt in some tables of this type:
Warning: InnoDB: Index 'ix_linear_pole' contains 1683314 entries, should be 1683294.
However, the check does not run to the end and for one specific table the whole mysql server crashes again.
UPDATE: I found out that the error is in the loaded command in the InnoDB buffer, but I don't know how to delete it. Each time I turn on the server, a command in the buffer crash it.

Answer 1

After several hours of research, I found that MySQL was failing to load InnoDB Buffer. The easiest way was to add a command to my.ini
innodb_force_recovery = 4
However, the database is started only for SHOW data. Using mysqldump, I backed up the data without indexes. Then I deleted the database from the server, I also deleted the logs and database data from the system (C: \ ProgramData \ ... \ MySQL \ data \ ibdata and iblog0 and iblog1). Then I stopped MySQL and removed innodb_force_recovery. The database then ran in but without data.
I uploaded the original data back using normal recovery and created indexes.
From that moment on, everything works without problems.
