Ubisoft Connect will usually crash at some point while I'm playing. I only notice it's crashed when saving the game doesn't work anymore (neither manual nor auto). I've tried alt-tabbing out of the game to re-start Ubisoft Connect, but the game doesn't re-connect. I don't know why this affects manual saves.

Here is some information from Event Viewer:
