Video Capture Device Bug - OBS Not Responding and no capture card image

This has to be due to the Nvidia Driver Update on the 27-28th cause then after the issue occured...Could a rollback to the old Nvidia Driver (Oct 12) temp fix this until a newer update?
That's what it was for me. I was suspecting it was that as I didn't start experiencing the issue consistently until after that update. I rolled back to version 522.25 and it fixed it.

Same problem for me with Elgato HD60 S+. For a moment it's working but then after few minutes freezing and after clicking on the not responding configuration window of the capture card it's OBS is crashing. My pc is running with an AMD GPU, not Nvidia. Anyone an idea how to fix it?

SOLUTION FOUND. If you previously used or currently use VSeeFace, Emiliana tweeted on Oct 27th about the latest NVIDIA driver (526.47) causing this issue. "Try uninstalling the virtual camera using "UninstallAll.bat" in "VSeeFace_Data\StreamingAssets\UnityCapture". If that doesn't help, downgrade the GPU driver."

This worked for me. Be sure to remove the VSeeFace Virtual Webcam components in your scene(s) and then try adding in your Video Capture Device.

Hello! Created an account just to confirm this also solved my issue. Rolled back to Nvidia 522.25.

On a side note, I also use VSeeFace but i have not touched it. Rolling back to Nvidia 522.25 is all I did and both my Video Capture Device properties and my VSeeFace are working just fine.

With 522.25 the problem appears randomly: start OBS one time, it's ok. the other cam or capture is missing.

So has there been a fix for this except for rolling back to Nvidia 522.25? Just want to be sure since I havent found anything else

Hello everyone, I just signed up to say that I found a fix that worked for me after all the above didn't so if you're on my boat, I found a vtube software that was the problem. So not necessarily VseeFace, look for something similar to vtube or anything with camera tracking and try uninstalling it to see if that helps. I have some other softwares like canon utility but they had no effect on obs crashing.

Also wanted to say that obs used to completely crash when closing aswell, always had to end process, now it's fine

I was having the same problem just now and, after some trial and error, it turned out that it was the USB connection's fault. Just plugged the capture card directly to the PC instead of a USB hub and everything works perfectly now.

I also remember having problems in the past when using USB cables of less quality than the one provided in the box, so maybe try that too if something fails.

For me it was the virtual camera from Live3D. The problem is, I want to use that virtual camera, specifically for streaming. So I would really appreciate a fix for this.

There's a deadlock bug in the unity capture plugin which is what Live3D is using for their virtual camera. They would need to incorporate this fix to prevent it from freezing during enumeration.

I wanted to add to this thread, I upgraded my card to a 4070 and so I didn't really have drivers to rollback to. Windows was up to date. I downloaded the oldest available drivers, uninstalled virtual cameras from the registry etc. Nothing was working, I'd get the same white box freeze trying to open camera settings in OBS. However, I followed what ItsAlexandrian suggested as I'd previously messed around with VSeeFace - thought I'd got rid of all the virtual cameras but apparently not. It fixed it for me (so far)! I'll be seeing if the updated drivers work now, although they just released yesterday so I am hesitant.
