`dotnet run` cannot run the project due to `System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string. (Parameter 'startIndex')` exception

Describe the bug

dotnet run is unable to run the program due to error but dotnet build works fine.

To Reproduce

1. Use dotnet 6.0
2. Create a new dotnet project by do dotnet new console
3. Write some random program (Here’s mine)

// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello, World!");

1. Run it by do dotnet run

Exceptions (if any)

System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string. (Parameter 'startIndex')
   at System.String.Substring(Int32 startIndex, Int32 length)
   at System.String.Substring(Int32 startIndex)
   at Microsoft.DotNet.Tools.Run.RunCommand.TryGetTargetArchitecture(String runtimeIdentifier, Nullable`1& targetArchitecture)
   at Microsoft.DotNet.Tools.Run.RunCommand.GetTargetCommand()
   at Microsoft.DotNet.Tools.Run.RunCommand.Execute()
   at Microsoft.DotNet.Tools.Run.RunCommand.Run(String[] args)
   at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, TimeSpan startupTime, ITelemetry telemetryClient)
   at Microsoft.DotNet.Cli.Program.Main(String[] args)

Thanks @KalleOlaviNiemitalo, for Windows PowerShell I found the environment variable DOTNET_SYSTEM_GLOBALIZATION_INVARIANT being true solves the issue as current workaround.

> $env:DOTNET_SYSTEM_GLOBALIZATION_INVARIANT='True'
> dotnet run

Folks - if you’re having this issue can you please comment (or edit your existing comments) with

• your system’s Locale/UI Culture
• the SDK version you’re using?

I think this was fixed in 7.0.200 by https://github.com/dotnet/sdk/pull/27566, so if you’re using 7.0 SDKs make sure you’re at least on that version.
