I have had this same issue and have use the following procedure twice, first on M1 Mac Mini that shipped with Big Sur, then on an Intel iMac Pro that shipped with Mojave, both are now running Big Sur 11.6. Both also failed to recognize the UltraStudio Recorder 3G on Thunderbolt 3 but are now operating normally.
First, on Mac Mini ONLY :
[*] Restart in macOS Recovery, login as administrator, and launch Startup Security Utility from the Select Utilities menu.
[*] Select your disk and login as prompted. Click Security Policy, select Reduced Security, and make sure both boxes below are checked.
[*] Click OK, enter password as prompted, then restart into macOS.
From there:
[*] Download Blackmagic Desktop Utility 12.1 AND 11.7. Unplug your capture device before proceeding.
[*] Open System Preferences > Security and Privacy > Click the lock and enter password.
[*] Extract v12.1, run Uninstall confirming YES to uninstalling drivers, if prompted.
[*] Install v12.1 but WAIT on the final prompt to reboot. In Security and Privacy, a prompt should have appeared. If one doesn't, wait a minute or so for it to appear. If it doesn't, click reboot and move to the next step. If it does, click Approve, then follow the prompt to reboot. The system will restart twice.
Then repeat with 11.7:
[*] Open System Preferences > Security and Privacy > Click the lock and enter password.
[*] Extract v11.7, run Uninstall confirming YES to uninstalling drivers, if prompted.
[*] Install v11.7 but WAIT on the final prompt to reboot. In Security and Privacy, a prompt should have appeared. If one doesn't, wait a minute or so for it to appear. If it doesn't, click reboot and move to the next step. If it does, click Approve, then follow the prompt to reboot. The system will restart twice.
Then, repeat AGAIN with 12.1:
[*] Open System Preferences > Security and Privacy > Click the lock and enter password.
[*] Extract v12.1, run Uninstall confirming YES to uninstalling drivers, if prompted.
[*] Install v12.1 but WAIT on the final prompt to reboot. In Security and Privacy, a prompt should have appeared. If one doesn't, wait a minute or so for it to appear. If it doesn't, click reboot and move to the next step. If it does, click Approve, then follow the prompt to reboot. The system will restart twice.
With both systems, after the final reboot the Recorder 3G was recognized by Desktop Video Setup and captured video into Resolve 17.3.1. That's technically a conicidence and not pattern, but I plan to test the same unit on an Intel 2018-ish MacBook Pro tomorrow and will report failures.
Good luck!
