I got this issue when i use: "react-native-reanimated": "^2.9.1", "react-native-gesture-handler": "~1.6.0"

   <Tabs.Container>
      <Tabs.Tab name="B">
        <Tabs.ScrollView>
          <View style={[styles.box, styles.boxA]} />
          <View style={[styles.box, styles.boxB]} />
        </Tabs.ScrollView>
      </Tabs.Tab>
   </Tabs.Container>

_This error is located at:
    in MaterialTabBar
    in RCTView (at View.js:32)
    in View

Just a guess but if you see the react-native-reanimated installation documentation that this may happen after installation and that you need to start with reset cache. (https://docs.swmansion.com/react-native-reanimated/docs/fundamentals/installation#babel-plugin)

So my guess is maybe do one of those:

• yarn start --reset-cache
• npm start -- --reset-cache
• expo start -c

At least it fix a "toString" error for me
