I'm about 70 hours into my game and really super enjoy the game. I've had bugs here and there, and one questline I couldn't complete (the Silver Shroud), but now I can't play at all!

I exited the pipe-entrance to the Corvega Assembly Plant, then re-entered. Loading took an unusually long time, and when it did load I proceeded to hear swimming sounds and slowly sink through the world.

I reloaded and I got the same issue. Then I tried going back a few saves--same issue! It happens on all my saves!

A friend suggested I noclip and fly up then toggle it back on, but that doesn't help. I always sink through the world.

Save me!

You know this happened to me on another game altogether. When you sink into the world can you bring up pipboy? If so try fast traveling. You have to try something that will interupt this code break. Time might help like say walk away and then restart game. Give the system a complete shut down or have you tried this yet?
