Having the same problem on Series X.
Noticed the DLC was installed on my external, not on the internal. Moved everything over and now the quest is missing. Also it's not visable from the Dashboard, you have to go into Gamepass to re-install it.
Had started the quest from the Longhouse mailbox.
Now it's not appearing in my journal. The Quest was definitely there previously. Because I noticed the icon is missing, but it wasn't yesterday. Before I moved around my installs, to the correct location.
