This has happened twice today,both times just before VPS update.
After clicking on OK button I saw VPS update notification.
I did Avast repair installation so I guess I can only wait and see if it is fixed.
Has anyone saw this error before ?

Fixed.

Actually it wasn’t fixed.I had to perform clean installation and so far it looks good.
I guess some file or something was corrupted.
