This version of Boot Camp is not intended... on mac mini 2018!

I installed boot camp on an external ssd (windows 10) and installed the drivers I've downloaded from Apple and everything was working fine. Then one day wifi just stopped working and now the device manager is showing the network adapter as unknown and when I try to install the drivers for boot camp again, I get the message "This version of Boot Camp is not intended for this computer model." The computer model is a 2018 mac mini.

Also, when I try to reinstall only the wifi driver, I'm not really sure which one it is. There's a BroadcomWireless (in the boot camp drivers folder) for legacy, win7 and win8 and they won't work.

Everything else still works fine, only the wifi dissapeared. Weard.

Any suggestions pls?

Thanks!
