Description
Description
<-- A clear and concise description of what the problem is. -->
We are rendering a rive file in our app that makes it crash c. 3% of the time. We only have the bug on IOS. We are on an expo managed project.
Here is more info on the crash, captured through Sentry:
EXC_BAD_ACCESS

Research direction
Start with the RiveRendererView and RenderContextMetalImpl entries named in the Sentry stack trace, then try rendering the provided rive_home_screen.riv file in the Expo managed iOS app. Done means identifying and fixing the intermittent EXC_BAD_ACCESS during rendering, with the animation no longer crashing the app.
