"react-native start" works, but crashes while "react-native run-android" is ongoing, even on a fresh project (bare workflow)

Running an app (created by "expo init appName" in Bare Workflow) on Android requires to first react-native start and then react-native run-android. What happens is -

1. In 1st terminal, I run react-native start (tried from VS Code terminal, normal terminal, each of these as admin too). It works fine.

2. In 2nd terminal, I run react-native run-android and the server crashes (in 1st terminal) and the 2nd terminal can either show error or show success.

In case of success, it's no use cause the server is not working so shows that error.

Unable to load script.Make sure you are either running a Metro server or that your bundle 'index.android.bundle' is packaged correctly for release.

In case of failure the error is (in the 2nd terminal, the one running react-native run-android)

the part showing module-name "expo-constants" is NOT always the same. It varies at times, but the general structure of the error is this. for example

I've tried (scouring the net, especially SO posts) -

a - delete node_modules and npm install

b - cd android and gradlew clean . No affect. I've tried this before react-native run and also in between the two mentioned commands.

I've tried these steps in various permutations for the last 2-3 days, but this is not solving.

I even thought that this might be due to the new expo version launch on 15th April, and maybe that's causing some versioning issues, so I tried with fresh projects made with expo init appName. No changes made to this fresh app, just tries to run it on the emulator. It works fine with expo start but if I try react-native start and react-native run-android, the same issues repeat.

One might note at this point, that the issue can be called cyclic in nature

Also, does it make sense to -

• start the server react-native start
• run react-native run-android, let the server crash and let the app install with error - "Unable to load script.Make sure you are either running a Metro server or that your bundle 'index.android.bundle' is packaged correctly for release."
• then try react-native start again.

I think (don't know for sure) it doesn't make sense to start the server later, but out of my many efforts , this worked twice randomly. Could NOT be reproduced.

My system Windows 10 here's my package.json (it's the one generated with a fresh app and is untouched)
