Saving Error Code 3

[quiet glen]

Getting Error Code 3 consistently when trying to save.

• Reproduction Steps
  Just go through my usual day. It didn’t really start happening until I spent the entire day (twice) mining. My save file is about 2 years old, if that helps.
• Repro Rate
  Every time, ever since I hit Fall 11 of Year 2. If I use a backup save to go back to Fall 10, I still get the Error Code when I sleep that night after mining all day. First time I got the error it was after midnight, and I saw in the past someone was able to go to bed earlier than that and not get the error. I tried going to bed at 10pm and it still threw the error.
• Game Platform
  Xbox PC Game Pass
• Game Version
  v1.2-1239
• Input Mode
  Keyboard and mouse
  -Save File
  I’m unsure how to do that with xbox pc gamepass. Following the PC instructions didn’t yield any save file folders unfortunately.

Repeatedly trying "Retry Saving" doesn't work. "Continue Without Saving" works, but it doesn't let me save the next unsaved day.

This is the message that comes up when I close the game and play the same save:

Update: I chose “Try loading the backup again”, and not only did it work, but I immediately tried sleeping and it actually saved. So I have no clue what’s going on. I was in the Earth mine using a bunch of dynamite.
