Crash on PC version at Tanalorr, Can't Get Back Into Game **URGENT**

I'm getting very close to beating the game. All that's left is for me to face Bode on Tanalorr, but as soon as I got through the cutscene to pass the Koboh Abyss and land on the planet, the game crashed.

I tried adjusting my settings several times, but now it's gotten to the point where I can't even access the save file anymore and the game crashes whenever I load it.

If someone knows how to fix this, PLEASE PLEASE PLEASE let me know! I REALLY don't want to have to start all over!!
