Hi @filmor. It’s a fresh install of .NET 5.0.11:

C:\>dotnet --info

Host (useful for support):
  Version: 5.0.11
  Commit:  f431858f8b

.NET SDKs installed:
  No SDKs were found.

.NET runtimes installed:
  Microsoft.NETCore.App 5.0.11 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

To install additional .NET runtimes or SDKs:
  https://aka.ms/dotnet-download

@DareDevilDenis Regarding the initial problems building from git, this is fixed now on master after people found the problem in #1613.
