Do you have WSL2 installed and configured on your Windows installation?
From Sails docs page:
Laravel Sail is supported on macOS, Linux, and Windows (via WSL2).
https://laravel.com/docs/8.x/sail
Try running this command from a terminal using the Windows Subsystem for Linux version 2.
As docs implies you should have WSL2 installed and with a Linux distro of your choice configured.
