Quick LogIn after gamecrash error

I tried to log in to lost ark and when my game crashed so I logged in and lost ark showed me a picture that my account is already logged in. I immediately stopped playing the game, I thought it was an error bug, even though I didn’t give my account to anyone, so after a few hours I tried to log in again and now I’m constantly getting an Error and throws me out of the game. Now still getting error after 2 days Server authentication failed. Please try again [10010]. Please help with this.
