Today qt5-webengine is upgraded from v5.15.2-5 to v5.15.3-2 on Arch Linux. Afterwards Anki fails to display any content in the window. Terminal output shows this recurring error, and Anki cannot restart the network service:

[*:*:*/*.*:ERROR:network_service_instance_impl.cc(286)] Network service crashed, restarting service.
