INDD files won't save after upgrading to OS 12 Monterrey

[PH_Red]

After upgrading my Mac OS to 12.7, INDD files won't save. Error message is that the "the file appears to be damaged." This happens with any INDD file I open, so it can't be a damaged file. I am able to save as into a different folder.

I also downloaded INDD v19.4. The same issue happens; unable to save, damaged file. 

Thanks for any help.

And after that can you save that new document successfully?

Maybe a folder access permission issue. Provide full disk access to InDesign and then try
