Stuck On Loading Sequence

[BrewsterRooster]

I haven't really came up with any major issues as a guest before, until today... Every time I try refreshing the page, checking on the Character List, or even try deleting my Guest State, it will either stay on the loading screen continuously, or receive an error saying that it "Failed to reset guest state" and "Bad control character in string literal in JSON at position 524277 (line 1 column 524278)"

This all happen when I tried to chat with one of my characters. They manage to generate two or three messages from the start, then my computer suddenly shut itself off (it's a old laptop that runs Windows 10, go figure...) Once I try to boot up Chrome which I use for Agnaistic, my background is there, but I can't access any of the Chats, Character List, or Avatar. I even try logging in, but that didn't work either. Just stuck on the loading screen, telling me to log out, which doesn't do anything.

It's been almost two weeks now and I still can't wrap my head around it. I decided not to tinker with it, hoping that my data and my characters don't get deleted. The only option I can have now is to clear my cookies...
