So my wife has been having the same issues as everyone else. Crashing after every day (auto saves and upon loading new day crashes to home screen). Also recently she lost access to her save file with hundreds of hours of progress. This morning I sat down and finally fixed it (I think).
Platform: XBox Series S
Game version: Most recent update downloaded to console, no game pass or subscription services from Microsoft.
This was timed with a console update for the XBox, which may have been the actual reason it works now (I stream Cult of the Lamb and was having crash issues as well so it is very possible the console had its own issues or memory leaks).
I enabled backups and loaded into the game 1 day back from her most recent save.
Before this I enabled 24Hz display in the consoles display settings.
I know this seems trivial and unrelated, but this is the primary reason it takes developers awhile to fix these issues, everyone's consoles are set up so differently that sometimes certain setting configurations cause unintended results that either the game, or the hardware cannot adequately support and causes problems such as crashing.
RESULT: The daily crashing at save no longer happens, and she has full access to her save.
So before giving up on the game make sure your console is fully up to date, and go through display settings, even audio settings, and make some changes and see if something helps.
Hopefully someone finds this helpful and others are able to re access data they thought was lost.
