I have a blackmagic intensity pro 4K, I got it working and been using it for months.
To make it work I installed the required stuff from aur, on the aur page it said it needs DesktopVideoHelper.service to be running, after starting it it worked flawlessly.
Occasionally after an update I had to set the service to autostart again, but that solved it again.
Today it didn’t work, I assumed it was the usual thing where I had to start the service again, however…
raccoon@trash ~ sudo systemctl status DesktopVideoHelper.service

It’s already running. I tried rebooting and I doublechecked that it wasn’t the card’s fault, to make it quick I booted windows and checked there, it works, so at least I know that the card isn’t fucked and that everything is plugged in correctly, now I only need to figure out why it’s not showing up on linux.
I tried using it on OBS where it’s not listed but I also checked the blackmagic program where it says that no device is detected.
I confess I’m a little frustrated because it’s one of the things I use the most.

You might want to consider posting the terminal output as text.
It will make it searchable by search engines and possible to quote if needed.
Just copy-paste-highlight and press Ctrl-E.
Did the issue started after the kernel upgrade to 5.18? If positive, it’s possible that the driver wasn’t rebuild for the new kernel serie and need to be re-installed/ rebuild.
Try to rebuild your Blackmagic AUR package(s), reboot and see if it will work.
I tried but sadly it didn’t work.
And from yesterday my pc has started having connestion issues and now I’m all paranoid that it’s all connected and my drive is about to leave this planet.
Also if everything worked under the latest 5.17 that you were using, you could perhaps reinstall / downgrade to that version and put off updating to 5.18 until its next updates.
Other users are having various issues also with 5.18 at the moment.
