"An internal error occured" whenever I try to preview PDFs in File Explorer, crashes and hangs

[cartonofmilk12]

I installed Adobe Acrobat through Creative Cloud to edit PDFs. There's a big issue though. Whenever I browse through File Explorer then select (not open or edit) a .pdf, I get a pop-up from Adobe-Acrobat saying "An internal error occured." Also, sometimes File Explorer crashes or is stuck loading. As soon as I select a .pdf, File Explorer just stops working and I get multiple "An internal error occured" error messages that pop up. 

Please help. I've already researched this issue and no solutions worked for me. Please do not recommend to uninstall and reinstall Acrobat, use the Creatigve Cloud cleaner, or grant permissions for Adobe Acrobat, I tried all three of these solutions and they DID NOT work.

Thanks.

The issue seems to be with File Explorer's Preview Pane. As a temporary fix, you can switch the view to 'Details pane' instead of 'Preview pane' and File Explorer won't crash or error messages from Acrobat will pop up.

In addition to this, I can open, edit, and dsave PDFs normally with Acrobat with no problems at all. The issue is with File Explorer.

This is not a correct answer. It is only a workaround. Please look further down in the comments for a real solution.

This solution worked for me:

The actual correct answer is in the other thread linked in this comment. It worked great for me. Just disabling the preview pane is a workaround.

The fix that someone found (without Adobe's help i might add!) doesnt work for everyone.

@adobe please can we have an update on this? You've been silent on this issue since september. The solutions mentioned aren't working for everyone. It's been months. PDFs are a staple part of my day to day, and they're constantly crashing my machine, not saving, not loading, not previewing, crashing programs etc etc. Whats going on, when will this be fixed?

Did you follow the solution on this discussion? https://community.adobe.com/t5/acrobat-discussions/quot-an-internal-error-occured-quot-when-clicking...

Yeah, there were no 'unknown accounts' for me to delete

[GlendonKuhns]

I had a whole pile of accounts with random strings for names. 

I totally agree with you though that it is unacceptable for Adobe to ignore this. @AnandSri

I've just had this response from Adobe:

Any more response from Adobe?

It is not my case, I still have the internal error problem, I have already tried all the suggested options, nothing works, I will have to change the brand.

[amitg615]

To which brand?

Greetings!
There are no unknown user accounts here.
I've managed to solve the problem changing .PDF mime type to Chrome, navigate through some files and switch back to Adobe Acrobat.
