Expected Behavior

(I'm trying to use my Mac in a similar way that I use a Windows machine for streaming with my camera.)

I have a Canon M50 digital camera. Canon has webcam software that turns this device into a webcam. Sometimes the camera stops providing an image. When I ran into this on Windows I would toggle the deactivate/activate buttons for the "Video Capture Device". These buttons don't exist on the Mac version, so I have tried switching the device properties to change the device from the M50 to the built-in webcam and then switching back to the M50. Sometimes this makes the camera work again.

But sometimes this toggling of devices cause a crash. There are no logs from the Help->Log Files.

Here is the Apple crash report:

Current Behavior

Crashes periodically when changing the camera device.

Steps to Reproduce

  1. Create an EOS Webcam Utility Video capture device on Mac.
  2. Switch the device to the builtin webcam
  3. Switch the device back to EOS Webcam. ... built-in

Anything else we should know?

I used this camera and Canon's webcam software on my Windows machine since 2020 with OBS virtual cameras. I'm in the middle of migrating to Mac, but there is some instability with OBS and/or the Canon Webcam software. Because OBS is crashing, I'm filing a bug here, but also trying to work on the Canon side to see if their driver has issues.
