Why are my shapefile layers not showing in QGIS?

One is a line I copied/pasted in a new layer from a set of height contours and the other one is a polygon layer I created by dissolving all features in another layer. In both cases, the layers won’t display unless the entirety of the layer shows in the canvas.
