PDFs no longer compatible with Photoshop

I've been using Photoshop as normal but for some reason if I save a photoshop PDF then close the file, I am unable to reopen it again. An error message will pop up saying that this document is not compatible with this version of Photoshop. I am currently on photoshop 2024 but I tried going back to 2023 and I'm running into the same issue. My computer is fully updated with windows/firmware/etc. and meets the system requirements to use photoshop.I've tried having other people open the files on their computers and they also get the error. I can't use photoshop if every file I close becomes a stuck as soon as I save. Has anyone had a similar issue or know how to solve this?
