Sorry, I dind’t read through your whole post. That’s probably an issue with some overzealous AV scanner or similar software. The updater is the same program as the installer, recompiled, but code wise exactly the same.
While the original installer version is whitelisted by most AV programs, the more invasive/annoying ones unfortunately fail doing their guesswork with each new version.
If you use anything else than Windows Defender, try to exclude the vorpX program from your scanner if it allows you to do so. That can prevent many potential problems caused by failing AV programs.
