Bug Report OBS detects cam but no preview

I have been using OBS for a few years now with no problems. I have been streaming pretty regularly over the past few months and all of a sudden my cam has stopped working for OBS. It works in all other programs. I have made sure all the drivers are updated for it. Uninstalled and reinstalled OBS. When i removed the source and made a new one as you can see in the picture below - it recognizes my camera and a red circle appears in the top left corner of my stream preview. I work in IT and this has me stumped. Any help would be greatly appreciated.

Reinstall the latest drivers for the webcam, remove and re-add it as a source, and manually set the resolution and FPS to values it supports.
