...a lot of ranty bullshit...
Please stop taking steroids, they're really bad for you and should only be used under qualified medical oversight.
Given how wine determines username, even your rants contradict you. If the recreated prefix is recreated consistently then - given how wine determines your username (by my reading of relevant part of ntdll) - you have a mess in your environment.
So, I'm not arguing you don't have a problem, but that's it's a very local one, looking more and more like a PEBCAK.
