When attempting to run the following command:

@deanchalk Good morning. Looking at the stack trace, error appears to be happening while inspecting package metadata via NuGet. So either NuGet had intermittent connectivity issues or your network blocks connectivity to NuGet. Are you installing this in company network environment. If yes, could you try switching to a different network and try again.

Kindly note that this issue is not with AWS .NET CLI extensions. You are executing basic dotnet tool install command provided by .NET CLI.

Thanks,
Ashish
