Stuck on "You have been removed from the group"

Hello,

On Dec 10th, suddenly, after successfully completing a timerunner dungeon via Group Finder, I cannot queue with Group Finder anymore. Everytime a new dungeon pops up I’m automatically removed from the group right after dungeon’s loading screen. Both Dragonflight and Timerunner dungeons don’t work.

What I have tried:

  1. Deleted WTF, Cache, Interface folders = no luck;
  2. Disabled all addons = no luck;
  3. Removed all buffs from toys = no luck;
  4. Leveled a new character = works!;
  5. Remix characters = works!;
  6. Logging back to Priest = no luck;
  7. Rebooting PC = no luck.

Setup, just in case but I’m sure this doesn’t matter:
i9-14900, RTX4080, 64GB RAM, SSD.
Starter Edition, Priest Capped (Level 20), Locked Experience.
