2024 PSD files not opening with 2020 as of today

[KE_DP]

Error - Could not open “myfile.psd” because the file is not compatible with this version of Photoshop.

Up until today I've been able to open files going both ways out of Lightroom - but now the party is over I guess.  Maybe a PS2024 update pushed through to cause this?

I need to run 2020 due to a legacy plug-in I use regularly - as well as some actions and other things that haven't been transferred over to 2024.  (Every time a new version comes out all my cusomtizations are left behind - but that's another story)

So what's the solution here - save as TIFF?  (bloat)

I'll frequently start out with something like generative expand or some other modern tool  in 2024 - save and then open in 2020 for all my retouching work... well - not any more - until I get this fixed.

Any other ideas?  Save as - an earlier (or universal) version doesn't seem to exist.

EDIT -

Temporary fix that worked is - save as TIFF to desktop - that TIFF will open in 2020 - then Save as PSD over the 2024 version file location (using 2020) - then trash the TIFF file.  This at least lets me get back to work!

@KE_DP make sure you are saving Photoshop files with "Maximize Compatibility" on.

...in which case it will open incompatible files flattened. But they will open.

I have to ask: what is it you want "fixed"? Should they stop introducing new features because those features didn't exist in older versions? The logical consequence of what you're saying is that all development should just stop dead.

I just had the same experience. 2024 keeps crashing. this is a simple b&w image. Really stupid it won't open it. IMO

[Kevin Stohlmeyer]

@david flaherty is it crashing with all documents or just this one b&w image?

PSD 2024 crashes. I just don't need all the new bells and whistles. Been using adobe since illustrator 88 and psd from get go...I get improvements, but at a certain point it becomes annoying.

Do you have a beta installed at all? Have you tried resetting your preferences?
