Back Error - Unable to open a file to be backed up

Hello Fellow Sagers & Sagettes!

I'm brand new to using Sage. I created a new 2021-2022 file and it has no data (File size 1KB). When I normally close Sage it back it up my 2020 - 2021 with no issues. 

When I close sage under this new file I receive the following error. Back up failed. Unable to open a file to be backed up.

Thank you in advanced!
