Cerberus Fighter Base bugged (ME3)

The mission for the Cerberus Fighter Base in ME3 seems to be bugged. I can run every other mission in the game it seems but when I land on Noveria the game gets really laggy for a bit. Then the dialogue cuts and the models for the enemies don't render correctly. You can play through the mission but upon completing it the game soft locks on a black screen and any attempt to open the "Load" menu at any moment in the mission immediately crashes the game. Kinda sucks considering this is linked to an achievement that I'm now no longer able to obtain. I don't know if this is because of the June 7th patch or not but I've tried several quick fixes and nothing has made any difference so far.
