Login Error-Bug *Gamebreaking*

Hello,

i have noticed a bug that does not allow me to log into my account from the game-launcher. It occures when i start a game, but for some unknown reason the game fails to connect to the server. To get a new connection i have to re-log into my account, but now i am told that my account can not be found. To fix this, i have to repair the game wich takes a lot of time, making me lose LP in the Process (due to Remake)

Does anyone have the same issues or does someone know how to get rid of my problem? (I am trying to reinstall the game at the moment to see if it will fix my Problem)

Edit: After reinstalling the game i am now getting a bug splat error whenever i start a game.
