Our application uses NEFilterPacketProvider to filter network traffic and we sometimes get a wired crash when removing/updating the network extension.
It only happens on MacOS 11-12 .
The crashing thread is always this one and it shows up after I call the completionHandler from the stopFilter func

I do have a DispatchSourceTimer but I cancel it in the stop func.
Any ideas on how to tackle this?
