Same issue here, seems that if the woman Theo starts her dialog and you don't stop and interact, the quest bugs out and gets stuck. Brendan is so close to the Fast Travel point that it's very easy to trigger the interaction of Theo without realizing it. There are a few quests that are close to this fast travel point which makes bug this quest. Please help with this, I've tried everything but to no avail.
I'd really like to be able to complete the quest as it's currently the only one I have unfinished, which makes it particularly frustrating, especially considering how many times I've had to go back and restart my playthrough because of similar issues with other side quests and/or gigs. Please help CDPR.
