Nice to hear that I could help you!

I honestly don't know how I discovered that fix. I think my first guess 
was the
image was just extremely underexposed.
Still I think that there is a problem with the exposure automatic and it 
just
needs a strong "push".

At the moment I cannot test further as I installed Linux Mint on the 
laptop
for my wife's remote teaching. I had told her what could happen with the
camera and how to fix it, but as it seems she only faceed the problem 
once when
it was too dark in her office turning on the light was enough to 
activate the cam.
