insert images and save file in keynote

Hello,

Thanks for your reply. Answers bellow:

Q: Does the above happen on every Keynote or image file? or specific ones? (could be a problem with this specific file)

A: it happens on every Keynote image (regardless of format: png, jpg…)

Q: Does it happen with new files? (similar to above)

A: Unfortunately yes, with new files too.

Q: Do any other applications exhibit problems opening or saving files? (could indicate a disk issue)

A: Disk has space and other applications work fine, with no issues. (Indesign, photoshop, powerpoint, word, pages…all good)

I really don’t understand the issue and it makes it so difficult to work.

Any ideas?

Thanks
