When you have 10.4.24 started up on your mysql datadir. Stop by issuing a sql "SHUTDOWN". Examine your logs to ensure that "Shutdown complete" is the last thing in the log.
Then swap back to running MariaDB 10.11.2 on that directory contents.
Okay, how I am doing in the XAMPP Control Panel a sql "SHUTDOWN"?
MySQL->Admin->SQL
SHUTDOWN WAIT FOR ALL SLAVES;
Sure, ensure XAMPP doesn't impose some very short timeout and kill it off, that would have the same effect as a crash.
Unfortunately, it does not work with the Shut Down of old MariaDB.
Neither with „SHUTDOWN WAIT FOR ALL SLAVES;“ nor with „SHUTDOWN;“. I obtained in both cases the message: unrecognized statement type. (near Shutdown). After the shutdown the following messages: 1 errors were found during analysis. Unrecognized keyword. (near "ON" at position 25) SQL query: Edit Edit SET FOREIGN_KEY_CHECKS = ON; MySQL said: Documentation
When I switched to the new Maria DB, I got again the message: Upgrade after a crash is not supported… What I did wrong?
