Hi there
Hope you are doing well and sorry to hear that.
What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 22.1.20142 installed. Go to help > check for updates and reboot the computer once.
Also try to repair the installation from the help menu (Win Only) and reboot the computer once.
You may also try to reset the Acrobat preferences as described here https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082
Also try to create a new test user profile with full admin rights or enable the root account in MAC and try using the application there and check.
Regards
Amal
