stuck on screenshotting on dell laptop

On Windows 11 PrtScn on its own might open the Snipping Tool instead of copying the whole screen. That's a setting, Settings > Accessibility > Keyboard > use the Print screen key to open screen capture. Turn it off if you want the old behaviour back.

Windows key + Shift + S is the one I use, lets you drag a box and it goes to the clipboard. Windows key + PrtScn saves the whole screen straight into Pictures > Screenshots. On a lot of Dell laptops PrtScn shares a key with something else, so try Fn + PrtScn if nothing happens. Did you check the Screenshots folder already?
