Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

All commands to be run in bash fail with the error
fatal error - CreateFileMapping S-1-5-21-2019365981-16661518-2324984931-1002.1, Win32 error 5. Terminating.

Changing sandbox-mode to workspace-write fixes the issue. And I have to run every bash command outside sandbox mode explicitly, asking permissions every time.

What steps can reproduce the bug?

  • Get git bash
  • have sandbox-mode = "workspace-write"
  • ask it to run any basic bash command like pwd like in the screenshot or run any bash based script or command.

What is the expected behavior?
