Unable to initialize the video I/O device

Hi there!

Recently my Decklink Mini 4K gets randomly disconnected during editing in Resolve.


This happens from time to time (4-5 times a day) during editing or grading in the edit-room or color-tab.
The Decklink Mini is still recognized by the OS (i can see it in the Apple System-Settings) and after restarting Resolve it will work again for some time.
I changed the TB3-Cable and switched the TB-ports on my mac, but this issues still appears.

Im on a MacPro 2019 (OS 10.15.2) with 28-Cores, 192GB RAM and Radeon Pro Vega Duo.
Decklink-Driver is the latest from the BM Support-Page and I'm on Resolve 16.1.2

Any ideas?? Thanks!!
