bitcoin core – Visual Studio Compilation errors in V21.1

I have successfully downloaded the source for Bitcoin Nodes V19 and V20 and built them in Visual Studio but get compilation errors when trying to do the same with V21.1. I have reloaded all dependent software packages (Boost etc) using vcpkg, reinstalled Visual Studio, redone vcpkg integrate install but it makes no difference. I am still able to compile and link V20 but not V21.

Is it possible the source code for V21.1 from GitHub is somehow wrong?

Anyone else had this problem?

Thanks,

Jon
