VIRB EDIT video export failed

I have a new VIRB360. I upgraded the software with garmin express.

I downloaded the garmin virb edit app to my macbook. I have macOS BigSur on a macbook pro

VIRB Edit 5.4.3

VIRB 360 version 4.20

I changed the firewall and allowed virb edit access

This error comes up if I try to export to a file on my mac or if I try to share to my youtube account. It is only a 3 second video. I set all the resolutions and quality low and same happened. 

Export of video failed

unknown error occurred during video exporting

Any suggestions?
