Hi there

Hope you are doing well and sorry to hear that

Would you mind sharing the version of the Acrobat DC and the OS 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 turn off the protected mode (Win Only) go to Edit > Preferences > Enhanced Security > Uncheck 'Enable Protected mode at startup' , turn off the protected mode and uncheck 'Enhanced Security > Click OK and reboot the computer.

Note: Please turn on the security after testing to avoid any security risk.

Also, try to add the file and the folder to the Acrobat whitelist. Go to Edit > Preferences > Enhanced Security > Add File and Add folder path > click OK and reboot the computer once.

Regards
