Thanks for the reply 🙏🏿 It's hard to reproduce because I can't figure out the steps but I'll try 🤔

@Bogdan-Belogurov Hard to say from the stack traces alone, could you put together a sample project exhibiting the crash? It would help a great deal if we could reproduce it on our end.

I've also been getting crashes coming from various places in MetalView.draw. Our project also updates geojson source frequently (in order to animate some symbol and model layers). Sometimes the app crashes, sometimes the app freezes without crashing. It's been hard to reproduce reliably for me, as it seems like whatever's causing these crashes is triggered somewhere upstream, but will try to isolate as well. One thing to note in our case, is that the crashes occur usually when we are animating the camera with a camera animator.
Here are a few of the stack traces from when the app was terminated when it became unresponsive.
