Debugger tools not fully connecting

React Native Debugger app version: 0.12.1
React Native version: 0.64.1
Platform: Windows
Is real device of platform: Yes
Operating System: Windows

I am working on React Native for Windows. I set up a basic app with RN 0.64 and redux toolkit to set up some basic redux. Here is an example repo: https://github.com/jeanmaried/rn-debugger-test

STEPS TO REPRODUCE
1. npx react-native run-windows
2. Run the app with the react-native-debugger app open so it doesn't open browser debugger
3. Debugger says connected to port 8081
4. React or Redux Devtools don't connect
5. App does not finish loading and stays on "Loading bundle." or "Connecting to Remote Debugger" screen
6. Metro server does not log an error.

I tried on RN 0.63 and RN for Windows 0.63 and it worked. I also tried on Android to make sure it was Windows specific and Android worked with debugger with 0.64, which is why I believe the error is related to either this app or React Native for Windows on 0.64 specifically. I opened an issue on RN for Windows too: https://github.com/microsoft/react-native-windows/issues/8325
