Missing bootcamp option after upgrading to macOS 15.6.1 - fixed

So this was something that happened to me a few months ago, and it seemed I might have to re-install bootcamp after losing my Win11 version following an upgrade to macOS 15.6.1. It turns out that as the bootcamp partition was still there, and as far as I could tell all the files were in place, all I had to do was reset my security options (via restart using command-R) on booting back to none/unsafe as the upgrade to macOS had reset the T2 security options on my mac-mini. Now holding down option on startup gives me back the ability to either go to macOS or Win11.
