iTunes keeps freezing every start on Windows 10

I recently did a fresh install of Windows 10.

Every time I start iTunes (I am on Version 12.2.2.25) it just displays a white screen and freezes.

If I start iTunes while pressing Shift and select my iTunes.itl Library File manually, it starts without any problems. Changes are also saved to the database.

But the next time I open it without selecting the file manually, it freezes again.

I reinstalled it several times, tried an older Version (did not work, because of now incompatible library file), tried starting it as administrator or in compatibility mode for Win 8.1 and Win 7.

I can't find users with similar problems on the Internet or here.
