Cant even install Minecraft.

Tried to login and instal minecraft but i have this error, ive serched in many sites about this but i havent founded any solution, also when I try to login in xbox to verify if the error is with my account it pop outs a panel and it disapears when im loged to microsoft store, Ive purchased MC 5 hours ago and i dont really know how to solve it, i would appreciate any help <3.

PD: Ive heard aboutalternative launchers and etc, but ive heard that some of these have virus but if there is any good i will download it.
