We actually keep a backup folder for stuff like this. Open it and sort it by date. whatever the last huge number was, move that to the main folder and rename it to save.sav. That will bring you back to the last 15 minutes before the crash

Just in case you need a visual. These are saves in the backup folder. The 3kb one is a sae from a brand new player.
The 269 is from the last autosave you got so just move that 269 and most recent one to the main folder and rename it. It'll auto fix that crash and your progress is back
