Freezing when I login

hey guys,

having an issue where my game freezes when I log in, as in after character select.
The thing that's weird tho is that its only affecting one of my characters, can log onto other characters without an issue except this one, which of course had to be my main.
Anyone got any suggestions as to how to fix this?
Thanks

has anyone got any suggestions? I've tried reinstalling the client, disabling all my addons and the unstuck feature on here but nothing has worked, not really sure what else I can do
