I saw below also

when I debug the code, both below are called
NEProvider.startSystemExtensionMode()
IPCConnection.shared.startListener()
Starting XPC listener was called.
The App registered was called.
Strange thing is that FilterDataProvider init was not called.
I still have issue. it looks like FilterDataProvider init was never called.
I attached the log for extension and firewall app.
extension.log
firewall1.log
firewall2.log
