Can't take Hi-res screenshots

Basically what the topic states. I’m hitting the ~, type HighResShot (I let it autocomplete), and press Enter. Nothing happens. I don’t even get the notification in the corner telling me the picture is saved. Please help Internet

Look There is button on Left side of Perspective Button on Viewport Click on that and select Hi res Screenshot New Window Will open then You Can Capture The Hi-Res Screenshots.
