1. Unlock KeePass
2. Lock KeePass
3. Open Zoom, start video in call
4. Attempt to unlock KeePass with KeePassWinHello via camera
5. Unlock successful
6. Video in Zoom freezes but audio works
7. After ~1 minute, Zoom crashes

A recent update to Zoom seems to have fixed this problem: Windows Hello now recognizes correctly that the camera is in use.

Unfortunately, its external applications issue, we can't do anything here.
