Adobe Acrobat freezes when trying to digitally sign

Hi Juan Esteban

Hope you are doing well and sorry for the trouble. As described the application freezes when you try to digitally sign the PDF.

Would you mind sharing the version of the Adobe Acrobat DC you are using? To check the version goto Help > About Acrobat and make sure you have the recent version 21.07.20099 installed. Go to help > check for updates and reboot the computer.

Also please check for any missing/pending update for OS and try updating it and check.

Please try to reset the Acrobat preferences as described here - https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-default/m-p/4792082 and see if that works.

Also try to sign the PDF online via Document Cloud - https://documentcloud.adobe.com/link/home/ and see if that works for you.
