An actual semiconductor engineer that works at ASML has uploaded a whole series of videos that debunk the existence of photons in free space[1]. https://www.youtube.com/shorts/V6G8ZZmeJzc

Quantum Mechanics is a set of mathematical tricks, shortcuts for numerical computation, that is all. People have become so enamored with the results of those computations that they've blithely ignored the limited scope of these shortcuts. You've found a nailgun, it's better than a hammer. That doesn't mean everything is a nail now.

[1] Essentially, "particles" like photons are a short-hand terminology and a matching set of mathematical shortcuts for the behaviour of waves in a potential well (or any cavity). It doesn't make any sense outside of that scenario, such as light traversing empty space. All of that behaviour is perfectly predictable with ordinary wave mechanics. No quantum woodoo is required.
