Make sure you have Emacs 26.2 or later, compiled with module support (--with-modules). Check the value of module-file-suffix: it should be non-nil. (This is currently a default compile-time option Emacs distributed with Homebrew.)
The other problem is that in practice, it’s surprisingly easy to write code that implicitly observes some state without having the proper dependencies, at which point glitches appear again. There’s typically no easy way to fully prevent these cases from cropping up, so some amount of vigilance is required to make sure everything is working.
