Hi leskabarl0pl0p! I'm sorry to hear that Watch Dogs Legion crashed and is now getting stuck on this black screen. Firstly, as listed in our known issues, the team is aware of the game crashing to the desktop on PC. A hotfix is scheduled to deploy tomorrow in response to these crashes! Secondly, have you tried verifying the game's files and completing the other steps listed here? They would be great to try to see if they get you past this screen, especially while waiting for the hotfix!
That makes it two of us my game went to a black screen could not move and i could still hear the npc's in the background. Can not continue my progress until a patch that fix this issue tried verifying the files, windows update,defragging the drive and even a ccleaner sweep nothing helped. Guys i really hope the 30 October patch fix the issue
