Plutonium

When I press play on any of the games, the console opens for a second but closes, then the plutonium menu closes right after, there is no error message so I have no clue how to fix it

i prestieged for another class slot because I was never satisfied with only the normal amount and now i cant get into any server games, ive deleted the game and reinstalled it and even made another account but its still saved, please help ive wanted to play this for so long
