doesn't let me join my friends game + doesn't let me connect to a microsoft account

i play on the ps4 and whenever i'm trying to join my friends game it continues to tell me that i'm unable to join no matter what. i have restarted the game, i have switched to the old minecraft and then switched back to the new one to see if would work and it did not. i thought it would be because my minecraft isn't connected to a microsoft account but it wouldn't even let me do that. every time i click to sign in with a microsoft account it says failure to log in.
