Decklink Fails if set to Decklink set to rec2020 and timeline set to rec709

HDR output is currently broken for decklink

Premiere 25.1.0

Desktop Video 14.4.1

Decklink output is fine in rec709

Decklink USUALLY works in rec2020 if the Sequence is set to rec2100, though sometimes only at 60p

Decklink completely crashes if the sequence is Rec709 and output is set to Rec2020

Also HDR metadata is NOT being sent over HDMI.

Not the equipmant as working fine in Resolve.

This used to keep functioning correctly without having to change preferences when changing colourspace

Hopefully this can be made to work automatically based on the Sequence setings, just like it does in Resolve.

Hopefully HDR support can be prioritised a bit more now that it is becoming a de facto deliverable for a lot of distributers.

Could be an AMD / Threadripper Pro / PCIe5 /  Windows 11 24H2 problem, or a BMD driver problem but I suspect it is and Adobe issue as After Effects has had poor Decklink support in recent releases as well. Fully appreciate it is low in the priority but hopefully someone can take ownership of this
