Maybe I am wrong, but I believe there is confusion between "New instance" and "New window" - in both cases, Chrome and Edge - will open a "New window" (with a selected URL) if the production browser (with all your working tabs) is already open. But if the production browser is closed, the "start" command or any desktop shortcut containing the "--new-window" switch will open the entire production browser, and the selected URL will be just one tab among all the working tabs. In my opinion, we could not consider one of the situations as an "instance"...
