Possible Macros Issue - can't save file

[chesca2024]

I've been able to save these files for many years. Now I'm getting error messages

 

[#2]

After such an error, if you reopen the file, is anything lost?

[#3]

No, nothing is lost after reopening the file.

This tends to happen on complex files with a long editing history. You could try creating a fresh copy of the file by copying the sheets to a new workbook?
