This was also my experience. My hardware combination:
Sequoia 15.1.1
MacPro5,1 (upgraded cheesegrater 2009)
DeckLink SDI 4K (PCIe)
14.5 doesn't work
14.4.1 doesn't work
12.9 doesn't work
12.1 works (both with Big Sur 11.7.4 and Sequoia 15.1.1)
Others have been posting that newer versions of Desktop Video work for them, but I think too many different problems are getting merged into this thread. Please pay attention to:
Are they using PCIe? not Thunderbolt.
Do they have an Intel Mac? not a Mac Studio M1.
I read a lot of posts about approving extension security. Different versions of Desktop Video seem to require some form of security approval in System Settings. It's not always in the same spot. The two spots are:
(1) General -> Login Items & Extensions, second list ("Extensions"). One appears under Cameras and another under Devices. Sometimes only Devices appears. Approvals here are toggle switches, so you can turn them on and off repeatedly.
And (2) Privacy & Security, just below "Allow applications from". Approvals here dismiss when you grant them. After you approve them, they vanish without a trace.
14.x versions required approval only in section (1). 12.9 required approval in both sections. 12.1 required approval only in section (2). But again, on an Intel mac with a PCIe device, only 12.1 worked, so only section (2) was relevant with my stuck-on-12.1 hardware.
In section (1) when I say "approval" I mean the switches default to "No", so you have to do something or the card won't work. There's another item that defaults to "Yes" so you don't have to approve it. It's present with all Desktop Video versions, under "General -> Login Items & Extensions, first list ('Allow in the background')". In one post, Blackmagic Support had told someone, "toggle 'Blagmagic Design Desktop Video' off then back on." I think I did this. I don't know if it helped.
Another thing I did that I don't know if I had to do: power down completely after uninstalling each version, not just restart. I reckoned the PCIe card could get into a wedged state if the wrong driver stack touched it, but I never proved that had happened. As others have mentioned there's a flash rom in many BlackMagic products that has to match the driver version, and the various drivers automatically update this flash rom when you change driver versions. I've seen a UI for this update: it lets you refuse and leave the card broken, it displays a several-minute progress bar. I didn't encounter that this time, maybe because I only tried one driver version that actually worked, or maybe because the process has become invisible? I did experience one boot where the card wasn't working, but then it started working after a few minutes. : (
For me this is the second most frustrating part of debugging this because I never know for sure that a combination of versions doesn't work vs. is just flakey, because of flash rom updates or some other reason. This could be improved by having Desktop Video Setup do the card flash rom update. There should be a single application within Desktop Video that lists all hardware the Desktop Video drivers are meant to support, validates the driver stack is working, and offers to fix common problems. This would actually be superior to fixing problems automatically because the automatic fixes will necessarily race with my declaring the driver broken and manually uninstalling it. Hope this helps.
That's the second most frustrating part. The most frustrating part is that accurate compatibility information for platforms that are in common use should simply be published, and deprecations should be mentioned in the release notes. Debugging this problem cost me more than the card itself.
