Did you ever see a file chooser dialog? At this point I would have expected a file picker dialog to appear, asking you to tell it where your Photo Mechanic application is installed. If not, I have no idea what libxpc is or why it would be asserting some odd code.
I have attached a plist file from my system that has the path to PM5 set in it. You can try and replace yours with the one from my system. My PM5 is at the following path:
/Applications/Photo Mechanic 5.app
If yours is in a different location (the above is the default) then you can edit the file in a text editor.
Note: none of this should be necessary, but I think there is something odd going on in your system.
Put the sample file in that same Library/Preferences folder as I told you earlier.
HTH,
