World of Warcraft stopped working

I played WoW with bottles since the release of Dragonflight - without any issues.
Two days ago I can’t Chat or join a Group. every Player is “Unknown”?
I resettet my UI - deleting WTF, Interface and Cache Folder. I installed completely new - 3 times now.
On my Windows Partition it works - but who wants that?
I need your help, please :frowning:
Here are some details to my system:

Host: Vivobook_ASUSLaptop M3500QA_M3500QA 1.0
Kernel: 6.3.3-arch1-1
Shell: bash 5.1.16
Resolution: 1920x1080
DE: Plasma 5.27.5
WM: KWin
CPU: AMD Ryzen 7 5800H with Radeon Graphics (16) @ 3.200GHz
GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series
Memory: 5625MiB / 15394MiB (36%)

Solved, I played a raid on Windows and than it worked again.
So I guess the problem was on Blizzard.

Best regards
