Dead Space 3 fatal bug (unable to play)

It started when I was in the weapon crafting arena 4/6/13.  -Whenever I save/quit the game freezes/crashes.  -Whenever I get to a "progress saving" area the game freezes/crashes -When selecting the data you wish to choose and it displays current percentage and whether it's Classic mode, Pure Survival, etc; It displays 0.0% and it does NOT display a mode. It is blank. Not Standard, Classic, New Game+. It is empty.  -I CANNOT make a New Game+, but Classic, Pure Survival, & Hardcore still appear.  -On "Progress & Unlocks" everything displays 0.0%, but when I started Chapter 4 the Weapon part and Circuit don't appear which means I've still got everything but suffering a literal game-breaking bug...like being unable to play it.  Has anyone ever experienced this before? Any solutions? As it stands the my game cannot be played and after putting 73+ hrs into and it's clear I enjoy it very much but I'd appreciate if I don't have to start over from square one (not likely) or pawn it. Severely not hoping for the latter :(.
