I have just realised that I have the steamapps install on a SATA SSD (D:) and the saves are happening on the M.2 SSD C: drive.
Which one is the likely one to be failing? I am guessing its C: restricting save access, but this is just my layman's guess. Can I change auto-save location to somewhere on ...

Any other ideas btw, as I am only running Windows 11? Do you know of any way to troubleshoot this on my end?

Alright, thanks.

I have a reoccuring problem with auto-saves crashing the game upon completion.

Seems to happen when I am doing something within menus during auto-save but this is a bit in-conclusive.
Sometimes the autosave can be loaded. Sometimes it produces an I/O error and wont load.

Thanks in advance!
