Attempting to open a .pdx file causes Acrobat to open as a process in Task Manager, without opening the Acrobat application itself. Acrobat is then unresponsive, and will not load when the user attempts to open a .pdf or open Acrobat via the Start Menu. The user must end the process in Task Manager before Acrobat will open again.
This issue first appeared in version 25.1.20756 and is present in version 25.1.20813. The last working version is version 25.1.20531.
Tested using 64-bit version of Adobe Acrobat running on Windows 11 25H2 build 26200.6899.
Workaround: If the user manually opens Acrobat before opening the .pdx file, the file opens as expected.
