Video from usb capturing device is green/pink, only in OBS

[Great-and-tiny]

I am having issues with the video from my DSLR camera. It's hooked up with a video capturing device to the USB port of my iMac. The video signal is without problems when using other apps like Quicktime or Zoom. But when I add the video signal in OBS (new source-> video capture device->usb video), the video colors are green and pink. See the attached screenshot.

Here's what I know so far:
- Internal iMac webcam video signal is working without issues in OBS (all colors)
- OBS on BigSur worked without issues
- I am now on Sonoma 14.5
- I am using OBS 30.1.2 (64bit)
- I've tried downgrading to OBS 27 but that didn't make a difference
- I've tried changing some settings but haven't seen any change to the video colors

Any help to fix this would be much appreciated.
