Trouble with Resolve 17.2.1 + Decklink Mini Monitor 4K

After a long wait and a stable system running Davinci 16, I finally decided to upgrade to Davinci 17 today as it is no longer Beta and it has a few updates already.
I have downloaded and installed Davinci Resolve 17.2.1 and upgraded all 4 machines in my facility.
3 machines are working just fine, but on the machine with a Decklink Mini Monitor 4K Pci card. Davinci keeps crashing everytime I try and load any media at all on the viewer. After a few tests I was able to relate this crashing with the decklink card. When I change the output card to None in the preferences, I am able to use davinci normally. But with the decklink set as my output card the problems repeat itself over and over again.
Nothing shows on the viewer and Davinci crashes.
I have already tried to update Desktop Video (I was in 11.6) to the latest version (12.1) but same thing happens.
I am on Catalina 10.15.7
Can anyone at Blackmagic give me some light?

Hey. I have issues too. Other Apps crash when they try to access the PCIe card. Did you ever solve your problem?

Hey guys, I am having this same issue. Did you guys ever find a soluation?

Yes. Try other driver versions. Even on MacOS. Driver must match hardware and OS version (Decklink 4K Extreme on 10.15.7. works with Desktop Video 11.6 only in my case).
