Blackmagic UltraStudio Mini not connecting

[Axmactual]

I'm using a Blackmagic Design UltraStudio Mini Recorder to connect to OBS. When I have my camera output set to 1080i it connects just fine, but when I switch the output to 1080p, OBS doesn't show the connection. Blackmagic desktop video setup shows that it's connected via HDMI and is set to 1080p, but nothing comes up on OBS.

For reference, the camera I'm using is a JVC GY-HM170UA 4k Camera.

The firmware on the device may need to be updated. I had to do this at one point. Install the latest version of Desktop Video from https://www.blackmagicdesign.com/support/family/capture-and-playback
