Infinite loading screen with ELVUI

Hello so I'm using Elvui on the Frostmourne server but yesterday I couldn't login at all, it gave me infinite loading screen so I disabled it and now I can log in and everything but my fps is very bad and got random lag that has never happened before.
I have Deleted the Cache and reinstalled elvui and everything like that but doesnt work.
I had Bartender first but that stopped working for me, it wouldnt give me a ui at all and when I go to options there is nothing there.

Pls I just wanna use Elvui again.
