Summary:
I tried to go back to the main menu via the "Quit without saving" button and encountered a crash. Upon trying to reload the previous manual save, the game crashes after "Loading items" is reached on the loading screen. An autosave which was made 18 game-days before the manual save also exhibits the same behavior.

Additional Info:

• The uploaded file is the manual save.
• A computer restart doesn't provide any different results.
• I also tried loading the save on a different computer. Crash still occurs.
• DFHack was not present in installation.
