@KarthikV0631 I suggest you open a support request and have this looked at by support. It certainly seems like an issue with PNF that needs examination. If you do that, please note the INC here. Barring any other recent changes, you seem to have the correct PNF version that would work with the OS Build you are running. One more test you can do is to create a simple project where you interrogate a different application. For Windows 11, I like to use C:\Program Files\Windows NT\Accessories\Wordpad.exe as it is simple and yet also not likely to be used for anything else (like Notepad). I would test to see if you can interrogate it and if that project gives the same error.
