Hi Frank,
AFAIK you need to first initialise an instance of QgsApplication.

In fact, if you look at the the test_qgsblockingnetworkrequest.py, it begins
with app = start_app()
start_app (and stop_app) is defined in qgis.testing.

So you could try

import qgis
from qgis.core import QgsApplication
from qgis.core import QgsBlockingNetworkRequest as bnr

qgs = QgsApplication([], False)
qgs.initQgis()

r = bnr()

Does it crash?

Best regards.

Andrea
