When I add a new layer to a QGIS project it is often not visible in the viewing pane, although it is visible in the side Layers Panel.
I would like to make the layer visible and have tried to use the mouse to drag and drop the layer to the top of the layers panel. This however crashes the programme. The only work around I have found is to remove the basemap raster layer and then reinstall it.
I have attached a screenshot which shows the 'boundary' layer in the layers panel but not visible in the main viewing pane.
