MySQL startet nicht

[MFeldhoff]

Seit gestern Abend kann ich MySQL nicht mehr öffnen. Im XAMPP Shell wird mir eine endlos lange Fehlermeldung angezeigt, die ich hier gar nicht wiedergeben kann. Daher hier nur der Anfang...
Bin völlig überfordert. Kann mir bitte einer helfen.

Probiere bitte mal folgendes, das hat bei anderen schon zum Erfolg bei genau diesem Problem geführt:

Öffne den Ordner "\xampp\mysql\data\"
Lösche die Datei "multi-master.info"
Lösche alle Dateien deren Dateiname beginnt mit: "master-"
Lösche alle Dateien deren Dateiname beginnt mit: "mysql_relay-bin-"
Lösche alle Dateien deren Dateiname beginnt mit: "relay-log-"
Lösche alle Dateien deren Dateiname beginnt mit: "ib_logfile"
Lösche alle Dateien deren Dateiname beginnt mit: "aria_log."

Versuche nun MariaDB zu starten.
