Toxic players usually ruin a gaming experience, and the best way to deal with them is to remove them from your gaming list. You can also inform the game support and share the details of that particular gamer with other players, so the toxic player is pressured to either change their behavior or quit playing altogether.
If this does not work, then mute or block the toxic player. Play your game and focus on the tasks. Be positive and achieve the goal. If possible, report the abuse.
