Python cannot start a file

os.startfile either gives "UnicodeError" or "FileNotFoundError". How to fix this?

I also used a "Try Except" in UnicodeError, but still UnicodeError.
I used this code:

import os
os.startfile("C:\Users\Me\AppData\Local\Microsoft\Windows\WinX\Group2\Run.lnk")

I expected that Run (Windows + R) should open
I got a "FileNotFoundError".

I checked the file in location and it was there. I tried forwarding the slashes and the problem still persists.
