ProBuilder script standalone build exceptions

Hey folks,

Having a bit of a nightmare at the moment - my project is working as intended in the editor, but when I build & run it, one specific script seems to just not work any more.

The script in question is supposed to - when a button is pressed - briefly disable the player movement script, then modify a ProBuilder mesh (turns a straight tunnel into a twisted tunnel, like in Ocarina of Time), then enable the player movement again. Theoretically it isn't that complex, & as I say it runs perfectly in the editor.

What currently happens is that the player movement gets disabled, but then nothing else happens & movement is never enabled again. I've noticed that changing my Start() function to OnAwake() makes the button do nothing at all, which is... interesting?

If anyone has any insight at all into why this would be breaking specifically in build (I haven't built much in Unity at all, most just worked in the editor, so I'm hoping it's something easy & obvious) then I'd be exceptionally grateful.
