The tool fails to capture the entire screen or monitor.
As shown in the attached picture it doesn't want to capture the entire desktop.
Use print screen key or press Alt+Print Screen to capture the active window.
As Oshino Shinobu mentioned the Print Screen key (labeled PrtSc on many keyboards) can do this, but it puts the image on the systems clipboard. This means you'll have to paste the image into MSPaint or another image editor if you want to save it as a file. That said, you can still just paste the image into Discord or whatever after pressing Print Screen Windows also has Snip-n-Sketch built in (the replacement for Snipping Tool), which has become my go-to. You can search for it in the Start Menu, or press Win+Shift+S to just start taking a Snip at any time. After taking a Snip you'll get a pop-up notification you can click to save it as a file, or as with Snipping Tool and Print Screen you can just paste it into an application that supports pasting in images.
The problem seems linked to varying screen scaling across monitors. In the example, one display was at 100% and another at 125%, but adjusting both to 100% or 125% fixed the issue.
