For me on the PS5, teleporting to the closest town did not correct it. I had to portal out to a different region altogether (I went to Kyovashad), and then the quest marker appeared on my map. I took the portal back and was able to continue.
lol...sounds like a skill issue...dont worry Vox Machina had an issue with doors as well.
This post basically says, "Leaving the area and coming back doesn't work for everyone; however, leaving the area and coming back works for everyone!"?
