[2022] Unable to pick up the brother in the quest 'The Twit Saga: Part Two'

I recently got the game and haven't had any important bugs until now. In "The Twit Saga Part 2" I cannot pick up the npc after I have spoken to the other npc. Because I can't do this mystery I cannot get the platinum trophy which is really annoying as it is something I always try get. It may be an issue related to update 1.6.0 as I have seen that there have been bugs with this mystery before that have been resolved. I hope they will actually see this and fix this as I presume I am not the only player that has and will have this issue.
