Problem with login and session ID problem

So this problem has been happening to me for over a month. And i don't understand why its happening but this whats happening.. i cannot stay logged in to my account even though i have it checked as "stay logged in" and every time i login and launch the game it says "failed to login invalid session (please restart your game) and i did that multiple times already... And it just does not let me stay logged in or join servers can you please fix this problem or help me fix this. Thank you. (sometimes i am able to join servers normally but Please fix this.) i also put 1.15.2 because i cannot select anything else. it's not a version problem its with the launcher and login issues.
