Photoshop : Could not save "Filename" because of program error on Mac

Question

Hello! 
I've seen this post a few times but haven't found a workable solution yet... I've been processing images in LR and then editing on Photoshop. I always work this way and have never really had any issues. I use Mac. A few months ago, I received the "Could not save 'Filename' because of program error" message. After clearing my scratch disk and clearing cache files from adobe library everything worked fine. This week, I've been getting the message daily and clearing the cache files, scratch disk, restarting photoshop, disabling generator, disabling 'do not save in background' etc. does not work. I have to stop working for an hour so, get back to editing, only to have the error message pop up after a few images. This is not ideal. Are there any other fixes that I can try? 
 
Thanks in advance...

Hi,

We're sorry about the trouble with Photoshop due to the program error. Would you mind sharing the versions of Photoshop and Lightroom you are using along with your computers macOS version?

If you are using Photoshop 2019 or 2020, you can try toggling ON/OFF the option for Legacy Compositing by going to the Preferences for Photoshop, then Performance. Once done, quit and relaunch Photoshop to check if it helps.

If the issue persists, you can try to reset the preferences of Photoshop using the steps mentioned here: https://adobe.ly/2Qzc0K3

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

Let us know how it goes!

Regards,
