Short description of error
I get rather random crashes when opening scenes here in the studio that link from other scenes. After investigating a bit further, I realised that blenderkit Add-on seems to cause the crash when calling bg_update in line 104, file bg_blender.py. The error message points to a threading problem:

Exact steps for others to reproduce the error
I can't provide the files as they are under non-disclosure agreement. It happens on loading a file right after starting Blender, but not every time. 2 out of 3 times it might load successfully. What the files have in common is that I am linking large collections from multiple files, and the source and target files are located on a network drive which might not be the fastest.

Please try to create new .blend files that you can share that allow us to reproduce the issue. Otherwise I don't see how I could reproduce this in an acceptable amount of time.

Guess then it's better to simply close the report as invalid. I won't find the time to setup such a scene that could be shared online for testing. As the problem only arised a few days ago I thought maybe there were changes to BlenderKit that could explain what's happening, but without a trace it will be impossible to track this down.
