Blackmagic Intensity Shuttle doesn't work on OBS 26.1.0

I had a similar issue with a UltraStudio Mini Recorder. It displayed video in Auto but would flicker. If I picked any resolution it green screened. I updated to Blackmagic Desktop Video 11.7 in case there were any firmware updates (none for my device), restarted and then updated OBS to 26.1. I recall something about pixel format being in the wrong range in logs. I reverted back to 26.0.2.

Interestingly, I have an Extreme 3D+ and a Decklink Duo, and upgrading to 26.1.0 resulted in a green window instead of the video feed, regardless of the input resolution. Rolling back to 26.0.2 did the trick for me.

@qhobbes seems to be on the right track. I'm using Decklink API 11.6, which works fine with 26.0.2.

Only errors I can see in my logs is:

08:36:59.445: decklink: Stopping capture of 'DeckLink HD Extreme 3D+'...
08:36:59.516: decklink: Starting capture...
08:37:02.479: decklink: Stopping capture of 'DeckLink HD Extreme 3D+'...
08:37:02.525: decklink: Starting capture...

On another launch...

08:37:29.124: Video Capture Device: data.GetDevice failed
08:37:29.124: Video Capture Device: Video configuration failed

After rolling back to 26.0.2, I saw that the Decklink APU version being used is far older:

08:57:43.177: Decklink API Compiled version 10.11.4
08:57:43.177: Decklink API Installed version 11.6

Confirm.
I have the same problem with the three BMD cards.
I went back to an older version of OBS

I changed the Color Range from Partial to Default and the flickering went away. I'm using the following settings in 26.1:
