After Catalina update with CC Photoshop 20.0.6 corrupted the PSD files I worked on.
Attached is a screenshot, I get the message "Could not complete your request because of a program error." I can create new files, open some psd's and other formats. You never know when it won't open the next time. Once it doesn't open, it doesn't open on other systems as well. I have done a clean install, deleted all prefs. No luck so far.

Could you post a PSD you're having trouble with so we can help troubleshoot? (url Dropbox or CC files)

Jeffrey, This first happened after I installed Catalina and updated photoshop.
I worked on a few psd's (which are exactly the same, had different versions of the coin)
One of them didn't open, so I thought it was a one off corruption. But as I tried other psd's some opened some didn't. Now I am saving as PSB (Just to see if that's OK, its OK for now)

Check this: Photoshop: File extension (ex. jpg) not changing during format change after upgrade to macOS 10.15 Catalina

Could it be that these are files that simply got the wrong extension (so they are not really PSD files)?

I also thought that might be the case (Although I was sure it was psd) I found a small app called GIMP-2.10 and it opens psd's. You can open it with all its layers with that app. So no, it is a psd and just doesn't open.

The fact that GIMP can open it does not necessarily prove that it's a PSD. If GIMP ignores the extension and checks the file format in another way, then it still could be a layered TIFF with a PSD extension, for example.

Hi Tolga, go to Preferences > Performance... and check "Use Legacy Compositing" 

This will be fixed in our next major update.
