Getting following error in outlog when I`d ran my game in Unity?

This is shader error

WARNING: Shader Unsupported: 'Hidden/Internal-DeferredShading' - Pass '' has no vertex shader
WARNING: Shader Unsupported: 'Hidden/Internal-DeferredShading' - Setting to default shader.

need help plz should I change the shaders or edit the shaders plz I need help thanx!!

Which Unity version? What build target? OS version? GPU & driver version? Anything else in the logs looking suspicious? Running on editor or standalone? Your question has so little info that it is very hard to give any answer.

My best guess would be that you’re trying to run on some ancient HW, not supporting the required shader features.
