[2022] [BUG] Can't complete "Twit Saga 2" world event

I've reached the "Twit Saga 2" world event in Lincolnshire, where I need to carry the drunken brother out of the camp. I killed the bandits in the camp, talked the the man, but the game doesn't let me pick up the man, he just lies down and there cen be no interaction.
Something similar already happened in another event where I had to carry a lame man up a hill, I got no option to pick him up. Loading a previous save resolved the issue. Not here. I reloaded several saves, quit the game, restarted the console, to no avail. Only thing missing is downloading the game again, not too keen on doing that because it's over 100 GB and I have poor internet
Is there any known workaround for this issue? It would suck If I missed the platinum because of such a small thing…
Thank you.
