Black screen and error when starting the "game_endlessrun" sample file

When I send play to start the game, the error appears: "520 warnings occured during compilation! Please open the console to get more information " the game window opens but remains on a black screen

I am using Blender LTS 2.83.12

Reproduce the problem by opening the "game_endlessrun" sample in Blender LTS 2.83.12 and pressing Play. Start with the console output for the reported 520 compilation warnings; done means the sample starts without that compilation error and the game window is no longer black.
