Can't save changes to Keynote Presentation

I ended up having to clean my mac and freeing up 20GB of space. It's possible there wasn't enough room to "save" the Keynote before. In any event, Thanks!

Please explain what you mean by clean my Mac:

you manually deleted files to gain extra storage, or you installed rogue software?

What files were deleted to gain free space?

Please never use cleaning, antivirus or optimising software. This kind of unnecessary software often deletes important system files necessary for the correct working of the Mac which can significantly degrade the performance of the Mac. You have no control of what files are being removed, reports in this discussion mention of loosing important Keynote project files.

Test if your Mac account is corrupt by adding a new user account:

go to Apple Menu > System Preferences > Users

click the lock button and sign in

click the + button

enter the required information

sign in to the new user just created and test Keynote

I have this same issue with all iWork apps. Sometimes it works ok, but generally I cant save, save as or export anything. In both safe mode and a new user everything works fine. If that means the Mac account is corrupt, how would I go about fixing that? I recently updated to Monterey and that fixed the issue very briefly...

Thanks
