Could not save as "File Name.psd" because of a program error

[p.simp]

Hi after recently updating to Adobe Photoshop 21 everytime I try and save a file it pops up this error message. 

I have tried my very best to problem shoot this by uninstalling photoshop and reinstalling it and nothing works. I have tried contacting Adobe multiple time and nobody answers the chat or the phone. Very frustrating when you can't save your work.

This usually works ... it's a pain, but at least you won't lose any work: hide all but the bottom layer, save the file, quit PS, relaunch, pick up where you left off.
