Can I make a 4K YouTube Video with my Canon R5 and Firmware 1.6

I made a video a while ago about having trouble using the Canon R5 for video. I made the video before the release of firmware version 1.6 for the R5. I updated my firmware and set out to use the R5 to video one of my trips to a covered bridge. Needless to say things didn't go as I had planned.
