Some processes showing as undefined

Hey there, I built a desktop app on top of this library:

I've noticed that sometimes a focused window will return `undefined` instead of a string file path. On Windows 10 I can consistently reproduce this with Task Manager (`C:\Windows\System32\Taskmgr.exe`). However, one of my users also gets this when running Open Broadcast System (OBS). Which works fine for me on my machine and shows as `C:\Program Files\obs-studio\bin\64bit\obs64.exe`. That user also gets `undefined` when the Task Manager is open too.

Is this related to running as administrator or something?
