The way your describing this, it sounds like the game IS using a different folder. OneDrive IS a likely culprit so maybe it turned itself back on.
Did you check if you also have a sims folder there ?
Does the save you made actually show up in the saves folder you checked (look at the file date) ? If not, it is probably somewhere else and that's the folder the game is using
As for the new/load button not showing, that's a known bug if you create a sim and not move him in.
Thank you! I will try this, hopefully it will work 🙂
