Edit Reason: added gmic

It is because the active layer (the one you are trying to sharpen) is not th same size as the canvas. Use Layer -> Layer to Image Size and try again.
By all means try the 'resynthesizer' plugins. The only ones I install and use are the two 'heal' plugins. At least one of them (can not remember which, maybe enlarge) does not work.
Using the Gimp Appimage. It comes with a whole section of sharpening algorithms in G'mic. Look in the 'Details' section. Maybe try the Sharpen(gradient) filter.
