Xbox shutting down

Hi Mojang, so I have a problem since December 2020. My xbox one x is shutting down ( just on minecraft)  sometimes when I play on my realm or when I open the game and the mojang logo comes up or when the main menu shows up. Sometimes it shutts down 2-3 times in a row and I dont know why. I tried to reinstall the game but didnt fix the issue. Its very annoying and I cant enjoy the game, pls fix it.
