[Qgis-user] layers not displayed in the layer window

[Yoann QUENACH DE QUIVILLIC]

I had the exact same problem some time ago. The layers are present in the
QgsProject, but not added to the QgsCanvas, so they don't appear in the
Layer Panel but the entry is there in the Layer Styling Panel.
You can use PyQGIS to solve it
Here is a simple function that iters over the layers in the project, and
removes the layers not present in the canvas:

def remove_odd_layers():
    for layer in QgsProject.instance().mapLayers().values():
        if layer not in iface.mapCanvas().layers():
            QgsProject.instance().removeMapLayer(layer)

remove_odd_layers ()
