The common quantum mechanics “paradoxes” are induced by 4 main misunderstandings.
1. A wave function is of a particle.
Wrong.
…
2.1 A system's wave function exists in physical spacetime.
Wrong.
…

~ in the experiment-setup design, no measurement device is allowed to exist to provide a definition of different possible values of X

2.2 A superposition state is a physical superposition of a physical state.
Wrong.
“Quantum state” is a misnomer. It is not a (physical) state. It is a (mathematical) property. It is a system property (of a physical variable) of an experimental-setup design.
“State” and “property” have identical meanings except that:
State is physical. It exists in physical time. In other words, a system's state changes with time.
Property is mathematical. It is timeless. In other words, a system's property does not change. (If you insist on changing a system's property, that system will become, actually, another system.)
For example, “having two wheels” is a bicycle’s property; but the speed is a state, not a property of that bicycle.
superposition state
~ physically-undefined property
.
In the phrase “superposition state”, the word “superposition” is also a misnomer.
A superposition state is not of physical waves, nor of physical states. Instead, it is a superposition of physical meanings of some variables in a physical system.
a physical variable X is in a superposition state
~ X is a physically-undefined property (of the physical system)
