i hade the problem of instant freezing after i chose my char. In my case, deactivate windows fastboot helped. u can check if this works for u by shift klick windows icon and shift click shutdown. this force your pc to shut rly down and start without fastboot. if it worked, u can permanently deactivate fastboot in the windows 10 system setting -> hardware and sound -> energy options -> systemsettings (or google for the howto).
