Hope you are doing well and sorry for the trouble and the unpleasant experience. As described the Adobe Acrobat is freezing.
We need some more information for a better understanding:
- What is the workflow/steps you are doing, that leads to application freezing?
- What is the version of the OS and the Adobe Acrobat you are using? To check the version of the application, go to Help > About Acrobat and make sure you have the latest version installed. Go to Help > Check for Updates and reboot the computer once.
- Is this a behavior with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. Also, if the file is stored on a shared network/drive, please try to download it to your computer locally and check if that helps.
