My game opens in window mode and my graphics settings are changed???

epdaly11​  I wrote a guide for missing content here that covers the various OneDrive options:

[CURRENT ISSUE] Sims 4 saves/user content disappearing (PC) | EA Forums - 11838402

Some users report that one option doesn't show up for them, perhaps because it's not available in certain versions of Windows 11.  So if that's the case for you, just choose something else.
