since I updated from digiKam 5.0 to 5.1 some days ago, digiKam does not start anymore on my Windows 10 machine. Here are my observations:
If I try to start digiKam, no UI is showing up. In Windows Task Manager, I observed that the process is running, but obviously get stuck.
Nothing happens after the process has reached the state shown in the appended screenshot.
Here is the DebugViewer output for V5.2.0: (which I installed today hoping that the behavior is fixed, but it is still the same...)

Even if I try to start it with admin rights, it stucks again.
The only way I can start digiKam is by deleting the library folder. In this case digiKam starts up and asks me to provide a new collection.
