Unable to Start Dragonflight Campaign After Race Change

Hello,

I recently performed a race change on my character, and since then I’ve been unable to start the Dragonflight expansion.

The introductory quest “The Dragon Isles Await” is not available to me. I’ve tried using Chromie to reset timewalking, but that didn’t solve the issue. Wrathion is not in the location where he should be, and there is no portal to the Dragon Isles in the Stormwind harbor and I don’t have the Lost Dragonscale either.

I’ve seen a few posts on the forums from other players experiencing similar problems:

so I’m hoping this isn’t anything too serious. I’d really appreciate your help in resolving this.
