Please try again - github.com has been having sporatic issues the past few days, I myself have experienced this issue and waited a while and tried again for the download to work properly.

I tried again, and it was the same question;When I was in the browser input: https://raw.githubusercontent.com/boostorg/boost/boost-1.72.0/LICENSE_1_0.txt this address, parse failed, so this should be the reason for my network, rather than VCPKG bug
