EOS R5 No display on screen

[Pat4]

While photographing Xmas lights outdoors, the screen on was an annoyance, so I changed some screen display option and now screen will not display at all.  
Anyone have this issue?  There is no screen display so I can't tell anyone what screen option I picked.d

Camera is near useless without the display.

Greetings,

if you review the manual, you'll see there's a option for "Screen".

If you don't want to do that, just reset the camera and it'll start working again.

Look in the viewfinder, the menu will appear in there. You can go back to the setting where you turned off the back screen and choose AUTO1 to make the camera auto switch screens. 

in the future you can just fold the rear screen in to the camera to stop it illuminating at night rather than switch it off in the menu.
