I stumbled upon this problem and I don’t know if it is a known bug but I couldn’t find any related info.
When I set the game(exported to desktop)to fullscreen the keyboard stops working. I can still move and see the mouse cursor but that’s all.
Yes, that’s what I’ve been doing and it happens with all the examples. The problem is that each time I do it I have to force restart the pc because the keyboard doesn’t respond at all.
I noticed it also happen in window preview mode with larger resolutions like 1280x720. The only way to make the character move is to move it fist in the scene preview before launching the preview in window mode.
