You have been removed from the game ,Connection to server lost and other erros like sera and kinnerlake

I can’t play since the OP 4 update, I’m banned from the room, I can’t enter the store, kinnerlake errors and sera. I only managed to play an entire game until today
Is anyone else playing on the pc having this?
Connection errors with the server, just shameful that.
And the problem is not my internet, I have 2ms ping, high speed. I’m very sad that I can’t play my favorite game
