Can you clarify how you are hitting this error? Are you trying to render while your app is in the background? Or are you trying to render while your app is running in the foreground and you are hitting this error unexpectedly?

I also received this log，After testing, it is found that it only appears on ios15 devices, It seems that the app(metal) will be active after switching to the background in iOS15 (It used to freeze in a few seconds).
