Exactly.

Exactly.

Exactly.

Actually, it doesn't crash because of no symbols renderer. It just
takes so long to load the vector data that QGIS doesn't respond
anymore. When I click somewhere into QGIS after 10-15 minutes, Windows
told me that the app crashed and that I have to restart it.

24 shapefiles, polygon grid with 100 x 100 meters

QGIS3 (tested stable release and nightly)

Same behavior: it doesn't respond after some minutes.
There's no difference between no symbols and simple renderer.

Best,
