I just got off the phone with Adobe after 90 mins of remote tech efforts, to no avail, so they sent me here. Starting about 6mths ago, after years of use, my PDF files now freeze after opening. This occurs on all PDF files, and happens when I open PDF's from the file folder location, or whether I open them through Adobe. I am using Acrobat Reader DC version 21.11.20039.0 on Windows 8. Adobe tech support uninstalled and reinstalled, rebooted the computer, turned off any firewalls or virus software, updated, and did all many of things remotely that I wouldn't have the faintest idea how to recollect. I just tried a prior forum suggestion of going through the regedit files and creating new cServices keys,,,,no change. I am hoping someone here can give me some guidance please. Thank you in advance!
the same is happening to me, Acrobat Reader freezes as I turn it on in my 2021 iMac, I have yet to try to check firewll and turn off virus software. It works on my older laptop though...
Update the Reader DC app to version 22.001 and check if the issue persist
Please check the update for Adobe Reader, Launch Reader> Help> Check for updates
If that doesn't help, you may please refer to the help document and follow the troubleshooting- Troubleshoot errors, freezes | Adobe Reader | Windows
