[PC] Mass Effect Legendary Edition Crashing on Launch

I have nearly 300 hours in MELE. Suddenly, one day I just stopped being able to run any of the games. The initial loading screen shows for three seconds, then kicks me back to the laucher. I've already tried moving my Documents>BioWare>Mass Effect Legendary Edition files, redownloading vcruntimes, running as admin, and diabling overlays. After analyzing the crash dumps, each game is basically having the same problem: ExceptionCode: c0000005 (Access violation)

Any help is greatly appreciated.
