Game freezes when I choose "Save & Exit"

Three times in the past two days, when I go to the menu and try to choose "Save & Exit", the game freezes. Nothing seems to consistently cause it.

But there do seem to be a lot of other issues around saving. The game auto-saves at a very suspicious frequency. Sometimes it even starts auto-saving within 10s of loading the game. Other times it's only 30s or less apart. As referenced in other issues, there are severe lag spikes while auto-saving. I'm suspicious if I try to save and exit at a moment where the game wants to auto-save, it freezes.
