need help fixing it

Luma and Godmode9 still work when i try to use them but otherwise just stuck on black screen eternally, it somehow fixed it's self before and started working after i let it stay on for a long while like a couple of days but i tried to launch Twilightmenu++ and that's where the screen went back and now I'm stuck with a black screen when i turn it on again, Luma and Gosmode9 still work like before, and the black screen still occurs even when i take the SD out, replace SD or take battery out, also Rosalina menu still works as well.
