So I was doing the quest "A Nuclear Option" and this weird glitch happens where it pretty much prevents me from finishing the game. What's happens is once I put the fusion pulse charge on the reactor maxson says let's go or something along those lines then we get teleported. After that my screen is just white but I can hear a bunch of gunshots and my hud shows there are enemy's in the room, and almost immediately I go back into the loading screen then I'm back in the area where you originally jumped into the hole to the institute. It says I still haven't completed the quest because I need to talk to shaun and ingram but there's no possible way to get to the institute even after trying to get there, even jumping in the hole wont work. I pretty much can't do anything I can't even fast travel. I even loaded back up and ealier save where I was getting a part for prime and hoping that will work but it still didn't work. Can anybody help me ? My only other option is to go way back and choose another ending which I really really don't want to do.
