A/V output not working in FCP

The A/V output as stopped working in FCP. I believe it stopped working when I didn't update to Mac OS 14.1.1. I am using a Blackmagic UltraStudio Monitor 3G on a Macbook Pro M1 Max I can see the UltraStudio Monitor in system settings and it is working in Photoshop but in FCP I get A/V output: non found.


Does anyone have any ideas how to get it back working again?


Thanks

The solution to this was posted in a recent thread and involves activating legacy support. I think this is the relevant document:
