After almost 200 hours my save game became corrupt

I had an unarmed khajiit who I played as a monk. He specialized in restoration and light armor and with mods he was fairly decent. I completed the main quest and the vampire quest line as the dawnguard. I hopped on today and it said it could not load because it was corrupt. I killed Karstaag. I killed all the big bosses unarmed on max difficulty. I was going to start the dragon born quest today. Rip Yohkari-No-Sight. You could save others from death, but not yourself
