Unable to play my Demon Slayer

[BBD]

Describe the problem. Be as specific as possible!:
Whenever I log in to my Demon Slayer I DC in a few seconds.
But I am able to log in to all my other characters just fine.

I logged on yesterday fine and then while playing the Server Maintenance happened and I dced (didn't know there was one) and now I can't even leave map or go to storage to get my items I need for my other guy.

Images of problem

No image but I do have it a video, it is just going to take a while to upload...
"About 203 min. remaining..." and it is only at 2%

I had a similar problem once and I fixed it changing the ingame resolution in one of the other characters and then log in in the glitched one.
