Version 6.4 works on the same user.

2 lines of output, then closing

SOFTWARE/OS VERSIONS

Download and start DebugView from Microsoft. Start digiKam and give us the output in DebugView.

The cause can also be an antivirus program or similar if a simple program like kbuildsycoca5.exe is already hanging.

Another option would be a set environment variable that is relevant for Qt or KF5.

Debugview gives not a single line of output on my main user profile. 
A newly created user does fine. I just use the Microsoft Antivirus and already tried with it disabled.

I wonder what has been changed in the QT libs between digiKam version 6.4 and 7.0 to behave like this on my user profile. 

The environment variables are the same for my user and a new one.
Comment 4 kde 2020-07-25 21:37:23 UTC 
Forget to mention that I even tried to start the kbuildsycoca5.exe in Windows safe mode, just to rule out any running apps and other things. But still the same, works on a new user, but not on my own profile (a year old exactly).
Comment 5 kde 2020-07-25 22:05:47 UTC 
Tested a bit more and swapped the QT and KF5 libs from version 6.4. 
kbuildsycoca5.exe would run normally with the older DLLs. DigiKam obviously not, but at least it must be something in the libs that interferes with my user profile.
