i also ran the command :
mysqld --defaults-file=mysql\bin\my.ini --standalone --console

and this is the result

mysqld --defaults-file=mysql\bin\my.ini --standalone --console

Hi,

Please try the following fix. It already helped lots of users solving the multi-master Problem:

• Open your folder "\xampp\mysql\data"
• Delete the file "multi-master.info"
• Delete all files beginning with "master-"
• Delete all files beginning with "mysql_relay-bin-"
• Delete all files beginning with "relay-log-"
• Delete all files beginning with "ib_logfile"
• Delete all files beginning with "aria_log."

Now try to start mariadb the normal way again.

yes i have deleted all those files and it seems to have worked
the database server is back up again
now i will make a backup of my website

do you know what the reason for the errors are and is there anything i can do to prevent the same thing happening again?
