Getting a “not currently available” error when attempting to install Windows 10 on BootCamp on a MacBook Air 2020 running macOS Catalina

I tried to install a Windows 10 via bootcamp, but I got stuck with this error:

“Can’t install the software because it is not currently available from the Software Update Server.”

Been searching all possible reasons and fixes. there is even a suggestion that I have to wait hours, days, months. Which is ridiculous. I already spent a whole day with this but still no luck.

I don't have any VPN, I have 50mbps speed internet up/down (fibr), I downloaded ISO file from Windows, tried 3 types of version of window10 still didn’t work.

You can try installing without the use of the Boot Camp Assistant. The link below will download the Windows Support Software for your Mac.

Windows Support Software for MacBookAir9,1

This package will install the WindowsSupport.dmg to the /Library/Applications Support/BootCamp folder. You can mount this file to access the Windows Support Software files. You need to copy the $WinPEDriver and BootCamp folder to the root folder of the flash drive holding the Windows 10 files copied from the Windows 10 ISO. The flash drive will probably need to be ExFAT formatted.

Note: I determined the link the same way Brigadier from GitHub does. I did this manually without the use of Brigadier.
