Hope you are doing well and sorry for the trouble. As described the PDF is hanging when you try to create the PDF form.
- Would you mind sharing the workflow/steps you are doing to create the PDf form?
- What is the version of the Adobe Acrobat DC you are using? To check the version go to Help . About Acrobat and make sure you have the application updated to the latest version 21.05.20054. Go to Help > Check for Updates and reboot the computer once.
