I keep crashing every time I enter minecraft

Whenever I entire minecraft as soon as my auto login happens (I’m connected to WiFi) I crash instantly. It’s unavoidable and the only way to fix it temporarily is to uninstall and download minecraft. So far I did that and it started to crash over and over again. i cannot have these happening crash and Xbox bugs happening again. Is this an Internet, minecraft or Xbox problem I honestly have no clue.
