The rounded selection and the warning are both a result of feathering your selection.

Feathering essentially blurs your selection. That blurring errodes the corners of your rectangle, so what you see is a rounded rectangle selection:





The "marching ants" that show your selection can't show a partial selection, so only pixels that are more than 50% selected are included and you don't see the feathering. To see this more clearly you can hit the Quick Mask Mode button:





With that in mind, the warning makes a bit more sense. Since only pixels that are more than 50% selected are shown, if your selection is small enough that the "blur" of the feathering reduces the entire selection to below 50%, there is nothing to show.





Although you don't see any marching ants, there is a selection. Enable Quick Mask Mode again and you will see it (although it may be very subtle):





Simple solution: Set your feathering to "0".

Set the feather input to "0". That's all. Good luck.

Try to switch between these. That worked for me.

check your image resolution ie; file resolution ... you can select when it is in high resolution
