Blocked content for Artur

In 2021, I purchased rdr2 from Epic Games. When passing through the first chapters, I encountered the fact that when I tried to go through Blackwater, I was instantly killed and after several attempts I abandoned this business. But during the passage of chapter 6, it did not cause any difficulty. I wasn't being chased by Pinkertons, and I wasn't being shot in the back by a sniper. A year later, during the second passage, it turned out that it was impossible to get to Arthur in Armadilo. Tell me, how did I do it on the first playthrough?
