I am using QGIS 2.18.3 with a base map named Natural_Earth_quick_start_for_QGIS

I use Australian Albers EPSG: 3577

When creating a bunch of polygons on my base map, my QGIS suddenly stopped working. So I had to re-start QGIS and added vector layers that I was working on again. After retarting and changing the default coordinate to Australian Albers EPSG: 3577, almost all of the layers that I have just created previously do not show up, except for the layer named Cambodia Chamic1.

What seems to be the issue here? how to make them show up.

This is a list of the files associated with my created polygons enter image description here

I did check the Coordinate reference system of my layers at Properties > General > Coordinate reference system. All of my layers have CRS as WGS 84, EPSG: 4326 which is not the same as my chosen projection Australian Albers EPSG: 3577.

enter image description here

But the layer named Cambodia Chamic1 still shows up on my base map, whereas other layers having the same setup do not show up.

When I change the Coordinate reference system of all of my layers from WGS 84, EPSG: 4326 to Australian Albers EPSG: 3577, the layers that have not shown up still do not show up

and the only layer that's showing up (Cambodia Chamic1) suddenly disappears.

I don't know what's going on right now?

    Yes. I mis-posted my question on an unrelated site. So now I re-post it here so that my question may look right place, right time. I've deleted my post in stackoverflow.com

  • Are you sure all your layers are set to the same CRS as the projection? You can check this by right-clicking your layer and going to Properties > General > Coordinate reference system.

  • I had pretty much the same problem after QGIS crushing. I've just created the new project, added layers and everything worked fine. I also got some advanced styles, so I saved them and reload in the new project.

I might be wrong here but the file size of all your data is 1Kb, according to the picture you provided. It is possible (especially when in edit mode while the crash occured), that your data got corrupted (I had similar experiences in the past). This does absolutely not need to be the case or the reason for those layers not showing up, one can add a couple of polygons without increasing the file size and having CRS related issues is way more likely! But, with the layers loaded, could you check the attribute tables, just to be sure there is data? Or is that only a created list representation of the files? Then: nevermind...
