Cam Link 4K no longer works - works with every other application on windows (even streamlabs OBS)

Two days ago I was able to use my Cam Link 4K for my nikon d3300 camera without any problem. It is plugged into the right USB 3.0 slot, 4K utilty was changed to isochronous and I have followed quite a few other solutions to no avail. I have also uninstalled and installed the latest version of OBS / 4K camera utility.

I tested it this morning and found CAM Link 4k was able to run through streamlabs OBS no problem. Because I am running a dual PC setup through NDI I need to use OBS. Was wondering if there was anything else I could look into that could help me with this.

Whenever I "activate / deactivate" the source on OBS - it shows a frozen still of the camera view. Again it works with every other application and was working with no issue since saturday. There were no major windows updates I could attempt to roll back to as well
