Acrobat crashes when started up Mac OS Catalina

Hi,

As Acrobat crashes upon launch, does it gives any error such as "Quit unexpectedly" or something like that? If yes, then see the following suggestion, reset the preferences and rerun the Acrobat: https://helpx.adobe.com/acrobat/kb/error-acrobat-pro-dc-quit-unexpectedly-when-trying-to-open-acrobat-on-mac.html 

For anything else, you may try these steps-

1- Since its not launching for good enough time, so use cleaner tool for removal of app and its traces: https://labs.adobe.com/downloads/acrobatcleaner.html?22 

2- Reinstall the app and try launching it.

3- By any chance if its crashing with some specific files, then Navigate to Acrobat>Adobe Acrobat >Preferences>Security (Enhanced)>disable "Protected View" and "Enhanced Security">OK>close and reopen Acrobat
Note: these changes are only for testing purpose. Once tested, please change it back to the previous setting.

Thanks,

Akanchha
