Capture Error, Could not insert capture Test Session0328.CR3 into collection (Canon R6)

Here's what I do as a work around....on the left side of your Capture One Screen, underneath your camera settings, select the dropdown arrow to open up your Shoot Settings and then change your Image Quality to "Fine L", or "Normal L" for JPEG import and then shoot away. No, it's not shooting/capturing in RAW, but a high megapixel JPEG can be tweaked to your liking as well until you figure out the RAW miscue. Good luck!
