Black screen after changing resolution

I am having a problem with Forza Motorsport 7. To improve the fps of the game, i changed the resolutions of the game (from 1920 x 1080) to another one. Immediately after that, the game is all black and now i can’t see anything, not even to put the original resolution (1920 x 1080) back. I have already uninstalled the game and installed again, but did not work. The bug starts in the starting screen: I open the game through the microsoft store and it always starts ok, but in the starting screen, after pressing enter to continue, the screen goes all black.
