RDR2 Replay Mission Chapter 6 Glitch

I’ve completed the epilogue in the game and I’m trying to complete every challenge in Red Dead Redemption 2. I got to the weapons expert challenge where you need to stealth kill 9 enemies or something with a bow. I went to replay the mission where you break Eagle Flies out of jail (The King’s Son) and when the mission was loading, it suddenly stopped and popped up DEAD on my screen like I had just died in game. It did the sky loading screen and I received a million items for my horse like stimulant and reviver, and once it’s done loading I’m playing as Arthur again in free roam. I have my epilogue horse (rose grey bay Arabian) and all my weapons. I’m just Arthur. The pause screen is not making any clicking noises like it usually does when you cycle through the options. I’m still wanted dead or alive in the east and from Blackwater westward, but I guess I glitched the game. Has this happened to anyone else...?
