So after reaching the white house and seeing the cutscene play out I get a disconnection and booted back to character select screen. Once logged back in, I had to start from the beginning making my way back up to the white house. This was when I ran into the bug. As you can see from the image I've linked the area in front of the white house is now gated off and I'm unable to proceed.

Same here, the only solution for me was to create a new character.
But I did "ALT + F4" during the cutscene because there were no voices.
