I'm trying these steps, but can't show the run as different user option from taskbar, I'm using Windows 11.
Really can't think of buying a license, if I can't figure this out, at least update us if the dev team is considering to implement this option, I saw a thread over 1 year old and there hasn't been any update about this feature. It's essential for IT administrators.
Sorry to hear you are having issues. But, I am on Windows 11 V 22H2 OS build 22621.2428 with Start11 V2 Beta 1.01 and here what I get when I do those steps I mentioned above on Edge.
