Mysql and MariaDB will not start anymore

I use XAMPP some several years, but since this week Mysql and MariaDB wont start anymore.

XAMPP Control Panel v3.3.0
07:14:02 [mysql] Error: MySQL shutdown unexpectedly.
07:14:02 [mysql] This may be due to a blocked port, missing dependencies,
07:14:02 [mysql] improper privileges, a crash, or a shutdown by another method.
07:14:02 [mysql] Press the Logs button to view error logs and check
07:14:02 [mysql] the Windows Event Viewer for more clues
07:14:02 [mysql] If you need more help, copy and post this
07:14:02 [mysql] entire log window on the forums
