webcam locks up

I have a 4K camera that is plug and play, no drivers to install.

It looks ok using the Win 10 camera app.

At one point, I was able to get some images in NI-MAX.

But something goes screwy, not sure what leads to it, but clicking on it in NI-MAX results in a busy blue circle forever and I am forced to externally abort the task, which leaves some kind of garbage in Windows because I can't access anything after that (camera related).

Then the Win 10 camera app doesn't work.

Rebooting does not solve the problem!

I did a repair on all of the Vision modules and got the camera back.

However, when I try to use the Vision Express vi, it hangs forever and I have the same problems as before.

The camera is UC40M.  I'm using 32-bit LV 2020 in 64-bit Win 10.

thanks

Matt

update: similar problems with 2019 Labview on a different PC (also Win 10-64)

When I allow a lock-up to run forever, it eventually gives up with the message 'Can't configure device.  Error unknown.'
