how to edit notebooks in OneNote that are saved locally and not synchronised. Getting the error message "This section can't be edited because it's in an archive format. Click here to enable editing"

Question

I have moved my notebooks from default notebooks location into another folder and then back to the older location after this error occurred. I think I might have also copy pasted files from backup folder to default notebooks location or vice versa. Actually some notebooks have duplicate sections with dates or copies like 1, 2 so i cleared them in either default notebooks location and copy pasted it to the backup folder. I was not really sure how OneNote functions so all this ruckus. It turns out now if i try to restore my notebooks from default location folder it gives me the error "section can't be edited because it's in an archive format. Click here to enable editing"

If i try to convert it to a section with pictures to 2010 (it says convert section or notebook to 2010) it gives an error again- "please verify you have permission to modify the file and have sufficient disk space"

I have spent the whole night searching for answers on different forum but didn't find any solution. Could someone please help me fix this? This is very URGENT

i am using a windows 11 system and Microsoft OneNote for Microsoft 365 MSO (Version 2406 Build 16.0.17726.20078) 64-bit
