Windows 8/8.1/10 Lagging after crashing

Hello, i'm just wondering why logging in takes a long time?

Like i have to wait at least 10s+ to go from login screen to channel selection and character selection and when I get to character selection, it doesn't let me in the game and just goes back to the login screen.

It started after I had crashed from the game, then when I tried logging back in, noticed that the log in took more than 10s, channel selection and character selection were also lagged.

When I even manage to enter the game, everything is just lagged and it'll just crash me back into the login screen.
