Description
I had some old abandonded virtual cams (personify and snapchat) configured on my Win10 machine.
Anything in Electrum that was supposed to open webcam would fail :
"Cannot start QR scanner: initialization failed", "Make sure you have a camera connected and enabled"
I thought it was a hardware issue. But then it worked fine in tails with the the same hardware so I looked more closely at the Win10 webcam config. When I realize there were unused virtual cams I removed them, and then Electrum worked fine.
Therefore, suggest that Electrum need a way to notice there are multiple cams - some of which may not be working - and offer a choice of which one to init.

Research direction
Start by reproducing the QR scanner failure on Windows 10 with abandoned virtual cameras such as Personify or Snapchat installed, then compare behavior after removing them. Trace the webcam initialization path used by Electrum's QR scanner. Done means Electrum can identify multiple cameras, let the user choose one, and successfully initialize a working camera.
