Minecraft Windows 10 stuck on red screen at load up

So the other day I was playing Minecraft with my friends! All was going well, and then the game crashed. I went back into the game, but it wouldn't let me in my friends world. Then I got out of the game and restarted my computer, and when I got back onto the game, all I could see was a red screen. I have tried Restarting my pc, Uninstalling the game, and even watched several YouTube videos. I would love some help!
