error: XDG_RUNTIME_DIR is invalid or not set in the environment

[jaywalker68]

Hi, When I run "sudo python camera.py" I get the error message in the title of this message. I'm using a Raspberry pi 5 and am connected to it via wifi through RealVNC on a laptop running Windows 11. When I run env | grep XDG I see "XDG_RUNTIME_DIR=/run/user/1000".
