我在这里有完全相同的问题，但在React Native，所以我会为那些需要它的人提出一个解决方案。该错误可能由react-native-webview和/或React导航触发。在某些情况下，就像我一样，你不想在整个app上禁用硬件加速，所以这里有一个变通方法：

React-Native-WebView

<WebView
  androidHardwareAccelerationDisabled
  source={source}
/>

反作用导航5

<NavigationContainer>
     <Stack.Navigator initialRouteName="HomeScreen">
          <Stack.Screen
            name="HomeScreen"
            component={HomeScreen}
            options={{
              animationEnabled: false,
            }}
          />
     </Stack.Navigator>
</NavigationContainer>
