P: Program error when saving, lag when zooming, changes not reflecting in document window (macOS)

Hi folks, I keep getting a 'could not save "filename" because of a program error' when I try to save my work. Tried other formats and folders, nothing works. The only workaround I've found is hiding all my layers, saving, re-opening, making the layers visible and then it will work but this takes far too long. Surely there's a permanent fix? On photoshop 2021 on 11.0.1 BigSur if that makes a difference. Any help is appreciated.

Same problem here 😞 

I need some help here, up against some deadlines and now I can't save the PSD files? I have tried everything that I've found on here so far. No luck! What can I do, I really need to get these done and this is killing me. Time is money and I don't have much of either. We pay a lot of money per month for this product and I need it to work! Please give this the attention that it's due Adobe! TODAY!!!!

Adobe does not bother to solve the problem so I installed an older version and solved it.  That makes me think about why I'm still paying...

I am having the same problem here, when I try to zoom between 100 and 500 it just doesn't do anything, above that and under it works. It doesn't save, and I cannot use the clone stamp.

I am using a MacBook Pro with MacOS Catalina 10.15.7 with 32GB of Memory and Radeon Pro 5300M 4GB. Everything is closed, only Photoshop active.

I had to force close Photoshop because it wouldn't close showing saving errors, now I am just reverting the update. Hopefully the force close created a recovery file, otherwise I will just have to start again. So frustrating.

Unfortunately this didn't work for me

MacOs Big Sur

It happened to me yesterday and I have no solution about it.

If you go to your Adobe account or your Creative Suite Apps folder..in the list where you see all you installed apps...next to Photoshop there are 3 dots. If you click those, you get the option to install older versions! Yay!
