Sandbox will not run: Responds "Select an app to open 'Sandbox'" with Windows 11

I have docker installed and am trying to run Sandbox.

I enter the command from PowerShell: .\sandbox up testnet

It responds with “Select an app to open ‘Sandbox’”

I am on Windows 11.

Any ideas on how to fix?

Welcome to Algorand!

To use Sandbox, you need to use either:

  • MSys 2 / Git bash
  • or WSL 2 with Ubuntu

PowerShell won’t work as sandbox is a bash script.

See GitHub - algorand/sandbox: Algorand node sandbox

Thank you! This worked.
