2020-12-07 15:38:18 0 [ERROR] Aborting

I checked netstat -a -b -n
There is no other process listening on port 3306

tried using another port - no change

tried turning windows firewall off - no change

tried updating to latest wampserver64 version - no change

I cannot start the service wampmariadb64 manually, it aborts

what can I do, please?
