I facing an issue, very regularly that i wanna write it about.
ENVIRONMENT:
OS: Windows 11
TOOLS: XAMPP v3.3.0 (Apr 6 2021)
PROBLEM:
I am using xampp, with mariadb inside.
Mariadb wont start, after i restart my computer.
This behavior is not always but often.
That makes me uneasy to put it on from laptop to a real server.
my.ini:
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# D:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is D:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id =1
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>

I have searched for an answer to solve the issue; here is how i am recovering my databases: repair-mysql-data.ps1:
# Based on this answer: https://stackoverflow.com/a/61859561/1956278
$loc = "D:\xampp\mysql"
$dataOld = "./data_old_$(get-date -f yyyy-MM-dd-hh-mm-ss)"
$dataOld_ibdata1 = $( $dataOld + "/ibdata1" )
$backup = "./backup"
$target = "./data"
$target_ibdata1 = $( $target + "/ibdata1" )
$targetTest = "./data/test"
Write-Output $( "Will go to dir " + $loc )
pause
Set-Location -Path $loc
Write-Output $( "Will rename data to " + $dataOld )
pause

I want to try the solution in https://mariadb.com/kb/en/innodb-recovery-modes/.
Could you elaborate on:
Accordiong to @Akina 's comment, I copied and edited "D:\xampp\mysql_start.bat" file as below and tried values from 1 to 4.
@echo off
cd /D %~dp0
echo Diese Eingabeforderung nicht waehrend des Running beenden
echo Please dont close Window while MySQL is running
echo MySQL is trying to start
echo Please wait ...
echo MySQL is starting with mysql\bin\my.ini (console)
mysql\bin\mysqld --defaults-file=mysql\bin\my.ini --standalone --innodb_force_recovery=1
if errorlevel 1 goto error
goto finish
:error
echo.
echo MySQL konnte nicht gestartet werden
echo MySQL could not be started
pause
:finish
Recovery results are negative...
bat file results:

I fixed this issue by writting a daily automatic backup code for every databases.
Hence, when the problem happens,
Here is the daily backup implementation i am using: github
