This just started happening after working OK.
I have recently upgraded to Windows 10 but XAMPP and MySQL were working fine till yesterday.
Now MySQL shuts down after a couple of seconds.
I've tried various suggestion offered in these forums but couldn't resolve (e.g. change apache and mysql ports, run xampp as admin and add service).
Please assist.

my sql error log:
