Did you solve this problem. I'm having the same problem with a Rebel T3i. It was working perfectly with the EOS utility. I thought it was a Zoom update that gave me the gray screen. I rolled back to the previous driver/install, and still have the same problem. Any luck?

I had exact same issue. To resolve it, you need to consent access to the camera by OS.
To do so, open Windows Settings > Privacy > Camera (on left) > Change/Enable
Some privacy cleaning AIO apps often disable those permissions, so be watchful ;-)
