I'm talking about the actual materialization of the particle. Not the probability wave itself. Dunno if it's the right term "materialization" but basically I'm saying when it's no longer a probability wave but it becomes a particle it appears at random places within the probability wave. The location of the particle after the materialization of the particle itself will be different forward or backwards through time? Does someone know?

Wavefunction collapse is a huge problem, and taken at face value make QM not reversible. Nobody is sure, but probably when you consider a bigger system that includes the experiment and the observer, the time reversion is restored. https://en.wikipedia.org/wiki/Quantum_decoherence https://en.wikipedia.org/wiki/Quantum_decoherence (Note that the observer in QM doesn't need magical properties like consciousness, in some experiments it is enough to place a brick in the right position.)
