I think I'm just going to waste a few hours of my life an start a completely new game and take it to the point where I can do Leviathan and see if it still happens. If it does, then we will know it is save related, but I sincerely doubt it is save related.
So, after starting a completely new game to test it out I still get the crash. The exact moment I stepped off the elevator it crashed, just as it had with my other saves, so I do not believe this is tied to saves. As others have stated, they've reproduced this glitch on two different computers. There is something corrupted with the game files EA is sending out.

To expand upon corrupted files, I believe this is a recent thing. The file origins sends out for Leviathan is either corrupted or it conflicts with other DLC from ME3. Reports of this started sometime in January, so I believe perhaps a more recent update is the culprit. Again, the fact that it happens at the same exact place every time and is so reproducable, I think this is a matter of a corrupted file within the .sfar file for Leviathan. It's probably a very small portion of that file, too, but it's still corrupted and causing a problem for many players like myself. Remeber, for every player that reports the problem, there are probably at least 3 others that have the same problem and haven't reported it.
