I was playing with some friends, we had just crashed shortly before and didn't realize that the game hadn't auto saved since landing on the beach, so we were going to speed run through the dialogues we had already seen. Host (not I) attempted to interact with Shadowheart in front of the locked door while a player was still connecting, and the host's screen went black. The other 2 players already connected got a server disconnect (as well as the third after his game finished loading). I reconnected and was able to interact in the game, however the Host was still black screened. I tried to shove the PC towards Shadowheart to initiate dialogue and nothing happened, nor could I interact with Shadowheart. Host had to close their game via Task manager, and upon relaunching was no longer able to access the in-game profile they had made. They would select to use the profile but it would not properly select after hitting accept in the menu. Host then made a new profile and was able to play just fine, but the save was then inaccessible (because we were too lazy to dig through files and manually move the save assuming that would work) and we ended up just starting a new play through.
