Game freezes and goes not responding on one character

[Lumio]

I've also been having this issue on my druid (21) near EC/WC zone line.

I created a new character and it doesn't happen at all. I think it has to be UI related.

I do have a tiny window I added a few days ago. I keep trying to close it but when it crashes and I open again its still there.

I'll try deleting my UI file.



UPDATE:
Deleted my log file and didn't work.
Deleting my UI file worked!
