LR CC 9.2 hangs on import if Logitech c930e webcam is connected to the computer

[Jim Garrison]

New installation of Windows 10 Pro x64 (1909).

i7-4790K @4.00 GHz, 32GB memory, 3TB disk

LR launches fine, and imported with no problems 2 days ago. 

Yesterday I installed a Logitech c930e webcam, and today, attempting to start an import produces the screen shown in the attachment (I blurred the folder listing).

Killing the process by clicking the close X and telling Windows to close it leaves the .lrcat.lock file, which has to be manually deleted.  I ran a catalog integrity check and didn't find any issues.

Since the only change from 2 days ago was installation of the webcam, I disconnected it.  Import now works.  Lightroom should be able to ignore unusable input devices, so this is a bug that needs to be addressed.

What is the best way to submit a bug report?

Well, after unplugging and re-plugging the webcam, the problem cannot be reproduced.

I guess I'll chalk this one up as a Heisenbug.
