Well i think it's another bug. The game freezes just before the boss of the first quest (offline mode)... It's strange and i don't know if it's just me or if you already get stuck at the end (just after the speech and the earthquake)....
I took a look at the rail and noticed that the two last pins were soldered for some reason, luckly I still had the rail of my broken joycon so after I swapped them I was able to use it attached to the console
