Hi,
Please check if the File is marked as final, Go to File → Info and check if "Mark as Final" is enabled. Click it again to toggle it off.
Also, if the file is on a Restricted Location, such as an external drive, network location, or iCloud, with sync issues, Excel may restrict saving. Try File → Save a Copy to a local folder first.
I’m eager to hear back and work together to find a solution.
