You should try to reinstall the Teams and then again try to sign in and when asked to save login, accept it. If it doesn't resolve your problem, then you can contact the support team.

Teams asks to sign into office 365 with my company credentials everytime I start the application. Why can't it automatically authenticate like the windows equivalent? Sometimes it appears to sign in an then by itself go back to the sign in screen when I'm not looking and then I'm signed out without even realising for hours until my team mates email me....
