After I make an InDesign document, if I don't make a PDF copy before quitting out of InDesign, the entire document containing placed images and text is lost when I quit out of it. Having the PDF allows me to see what I had done in InDesign, but I can't of course update or alter the PDF.

I tried tossing out the preferences (shift+control+opt+command (mac) while launching InDesign) and it didn't change anything, it's still giving me skewed images.

Any idea why this is happening, and how to fix it? I don't even know what to call it. It's a rather new problem, and it's affecting even old InDesign Documents that were not having this issue when they were created.

My InDesign is up to date (version 20.1) running on a Mac (version 12.7.6)
