Instead of scenarios or AI, why wouldn't it be the case that success invites more problems? You've got issues with immigration happening too rapidly for the population's taste, inflation devalues your accumulated resources at a more rapid pace, essential workers' pay isn't keeping up with FAANG, inequality is rampant, lots of homeless druggies appreciating your shelter & food bank infrastructure but locals are fed up, and also the next level up in government works against you out of envy or simple lack of appreciation for you contribution to the public purse. Power structures crumble because citizens get lazy and entitled, not knowing how good they have it, populism and self-interest rule the day.
Design success as the enemy of success, and you never run out of issues to solve. That said, it would be nice to see the winning endgame in real life for a change.
