After playing a few hours past my last manual save, all my autosaves now seen to be corrupt and when attempting to load any of them (either by selecting continue from the main menu or manually loading any of the 10 autosaves) the below message is received.

The operation was canceled.

My manual save still works but is about 100 turns prior so undesirable to rollback that far. I believe I've worked out where Gamepass is storing the cloud saves but I'm not convinced so haven't uploaded them as of yet. Diagnostic file attached but suggests it's not loading due to Could not find file "C:\Users\Mimmitar\AppData\Local\Temp\AMPLITUDE Studios\Humankind\XGPStorageContainer1888196347\Sandbox.bin"

No folder called XGP exists in that location.  If I could work out where the relevant files are stored in "C:\Users\Mimmitar\AppData\Local\Packages\AmplitudeSTUDIOS.Humankind_sm4da3szdwjfr" I think I'd be able to rescue the save. Any help appreciated.

Sorry for the inconvenience. Saves should have a .ctr file extension, at least on the Steam version, but I have to confirm with the team tomorrow for the Gamepass build.
