Intensity Pro 4K stopped recording in OBS

I have the Intensity Pro 4K set up with my Cannon M 50 Mark II, and have had great success using it in OBS for pod cast.

However when I turned it all on today, I get a message on OBS saying there is a NVENC codec error and I need to update drivers.

I have not changed any settings, but it has been a month or more since I recorded any footage.

The Virtual camera in OBS is functioning for use with Zoom and Microsoft Teams.

Any suggestions?

I was able to contact Blackmagic Support and the nice young man chased my problem down, it required an update from NVIDIA.

Very appreciative of the help I received.
