Adobe Acrobat Pro 20.013.20064 - constant 20 second freeze when input data in prepared pdf documents

I've been having the exactly same issue, I'm not sure since when. I'm used to acrobat freezing for a few seconds from time to time, it's a crappy app for a few years now, in my opinion. But the last couple of months, it's been nearly unusabel, exactly as you describe. 

This morning I tried something that I did a few years back when a similar problem was anoying me: I turned off internet conection on my computer. And guess what? It stop the freezing. 

I vaguely remember that the problem a few years back was with my login, and I had to login properly through the app (and no through Creative Cloud, as all other Adobe apps I use). I guess this time could be that too. I could try the indicated steps noted here by the Adobe employees, to try to help solve the issues, but between 20 seconds of hang a 1 second of response from Acrobat, I don't have the patience or the time, as this could easily take a whole hour or more just to try (sorry guys).

I'll just keep disconecting when I need to work with it, and hope the next update fixes it somehow.

Hi Nicholas,

We are very sorry for the experience and not able to reproduce the issue inhouse. In order to further investigate the issue could you please share 3-4 process dumps of the issue (captured during the hang) with us? 

Thanks,

Vinod

Hi Nicholas

Hope you are doing well and sorry for the trouble. As described the application with the new update is freezing for 20-30 sec when you try to fill in the PDF form.

I have tried to reproduce the issue on my end and its working fine. Would you mind sharing the version of the OS you are using? Please check for any missing/pending update and try updating the OS and reboot the computer once and see if that helps.

If the PDF is stored on a shared network/drive, please try to download it to your computer locally and then try to fill and check. Also please try to fill a different PDF form and check if the issue is file specific.

Please try to repair the installation (Windows Only) from the help menu and see if that works for you. Go to Help > Repair Installation.

Also, please try to turn off the protected mode for testing (Windows Only). Go to Edit > Preferences > Enhanced Security > Uncheck 'Enable protected mode at startup', turn off the protected mode and Uncheck Enhanced Security > Click OK and Reboot the computer.
Note: Turning off the security may possess security risks. Please turn on the security after testing

If it still doesn't work, please try to create a new test user profile in Windows with full admin rights or enable the root account in Mac and try using the application there and check.
