This configuration worked

SUMMARY
When scanning more than about 20 directories digicam crashed repeatably and in some cases Windows stopped with a Blue Screen and rebooted.

STEPS TO REPRODUCE
1. "Extras->Wartung" (engl. Extras->Maintenance?): Select a directory subtree with about 50 directories. 
2. check the box "Detect and recognize Faces": "rescan unrecognized faces"
3. The box "Work on all processor cores (when it's possible)" is checked

OBSERVED RESULT
Always: digicam crashed
Sometimes: Windows stopped with a BlueScreen




EXPECTED RESULT


SOFTWARE/OS VERSIONS
Windows: 10; Release 2004


ADDITIONAL INFORMATION
Workaround: When the box "Work on all processor cores (when it's possible)" was UN-checked, digikam worked fine

This configuration crashed again

It looks like that the option "work on all processor cores" is the reason for the crashes
