Hi everyone,
hope you had good holidays and that someone will be able to help me on this.
It's the second time I have this problem. Last time, I uninstalled xampp and re-installed it, but I've lost my databases. Somehow, the saves I've made didn't work anymore. So I don't wanna loose this one.
MySQL is not willing to open. Below the copy/paste of the "logs" informations.
Thanks in advance for your help!

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.4.25-MariaDB
key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=0
max_threads=65537
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 20295 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
