Personally, I try to design the solo mode for a game once the multiplayer version of the game is pretty much done. If you try to design the solo early on in the experience, it can be nice as you can solo playtest the game, but in my experience that means updating the solo mode and not being clear on what is an issue with the solo and with the overall game.
Second! I like to take lots of notes on the multiplayer game, with the different player types and ways to interact so that when I go to start on the solo game, I have a lot to work with. If any players interact in odd ways, especially ways you personally wouldn’t play, I’d write those down as well, as they can be super helpful in making a robust solo.
