I don't have any device supporting telephoto camera. I tested builtInUltraWideCamera and it worked well.

Ensure your camera is running, call start() function after creating a new camera.

The problem may be cause by filter chain. If one of the image sources dose not transmit texture, the metal view freezes. For example, see the code below. The imageSource should transmit texture each time before or after camera transmitting. If the imageSource stops transmitting, the filter will not transmit texture, so the metalView freezes.

camera.add(consumer: filter)
imageSource.add(consumer: filter)
filter.add(consumer: metalView)
