Adobe Rush Failed to Save to Disk Error

Having a new issues after several successful videos. Repeated efforts to export and save have failed. I have changed nothing in Premiere Rush, but I repeatedly get the failed to export message with no further informaton. Plenty of space on card and all media files are stored locally.

Beyond frustrated as this should have been a 15 minute quick hit and upload to IG that has turned into 2+ hrs and no end in sight
