I’ve got the same Mini PC as MG_2025 and I’ve got precisely the same problem with the Blue Tooth and WiFi drivers. I’ve done cold Windows 11 install and upgrade to 24H2 as advised, attempted to install the drivers you pointed to. No such luck.
What/Where are the appropriate drivers for this system?
