Photoshop 2021 "An unrecoverable problem has occured"

lambiloon,

I am an end user and not a developer or a frequent user of the Adobe Help forum (thank dog).

It would be infinitely helpful if Adobe's Community Professionals would keep this in mind when providing responses to users looking for help here. I don't actually understand your response to SplitImage224.

Two things that would make a huge difference -- and maybe reduce the number of times requests come in for the same problem:

• A screen shot and/or a link to help us with the solution  — you are far better informed about what solutions are available and where to find them
• Writing your responses in complete sentences with punctuation and predictable capitalization* — I am having a hard time figuring out what to do with the information you posted because I'm not sure what it means

If you make things easier for us, your job will be easier too!

Is this what you meant?

Remove Photoshop with the Adobe Clean Remove Tool.

   (Do you mean Creative Cloud Cleaner or AcroCleaner?)

Then install Photoshop 2020. There are some bugs in the 2021 version.

If you have multiple hard drives, install Photoshop on your main hard drive.
