.NET Core SDK 3.1.100 says it is installing but it never does & VS2019

I have installed Visual Studio 2019 16.4.0 which was suppose to install .Net Core SDK 3.1 and I have run the .Net Core SDK 3.1 to install the SDK. Both say that it has installed but there is no SDK folder for 3.1 and when running dotnet --list-sdks it doesn't show.

If I run dotnet --list-runtimes version 3.1 does show.

Anyone else run into this issue or have a suggestion to work around it?
