It depends on the context. Personally, the trigger points are:

- ever evolving problem domain research manifesting as architectural doubt

- underspecification

- unforeseen integration issues with host API or environment (pattern collision, resource collision)

- F.O.M.O i.e. ego corrupted view of the problem

- cognitive fatigue

I’m sure the list is as endless and diverse as the people who make software...

thanks! my point on it is related to when you really get stuck, stopped maybe overthinking. Your first point is also one common I see, related to architectural doubt.
