my game crashes every time i try to log into microsoft :(

howdy all !!

iʼve been having an issue for a few days now and iʼm honestly stumped on what to do? basically, iʼve recently bought minecraft properly because previously my money-less butt had to stick with APKs which worked and didn't have issues usually except when i load up minecraft and tap ʼsign inʼ it ... doesnʼt work? it just crashes completely ?

does anyone know how to fix this? my partners and i are wanting to play together at some point but we need to get my game working first. thank u !! <3
