You don't need a new save, try going there again after a couple of in-game days

This is what the error looks like. I would like to know if this is a part of the story or if it's an actual error which could have a negative impact on the game.
The "Rollback", "Reload" and "Console" buttons don't work. Only "Ignore" and "Quit" work
Whenever the "Shadow" appears the screen starts glitching for a second or two, but I'm guessing that's supposed to happen.
