I tried multiple solutions for the above issue.

1. rm -rf node_modules/ && rm -rf yarn_lock/ && yarn install && cd ios && pod install
2. checking out the specific process & cancel that thread/process by specifying the p_id
3. nmp audit --fix

None of the above solution worked for me except this command

After all you have to do
yarn add react-native-gesture-handler react-native-reanimated react-native-screens

Close bundler & shift +cmd + k on xcode and run the app by cmd + R

You can access the developer menu by shaking your device or by selecting "Shake Gesture" inside the Hardware menu in the iOS Simulator. You can also use the ⌘D keyboard shortcut when your app is running in the iOS Simulator, or ⌘M when running in an Android emulator on Mac OS and Ctrl+M on Windows and Linux. Alternatively for Android, you can run the command adb shell input keyevent 82 to open the dev menu (82 being the Menu key code).

After dev menu open, press Settings -> Debug server host & port for device fill with <your computer ip>:8081 then reload

Having the exact same problem. Dead in the water atm. I can't build any React Native apps.

#28786 Might be the same issue

@skaynetmen @abdulbasit1248 did either of you ever get it working?
