Bundles generated offline do not start running the RN app when executed (white screen on version 0.69+)

[AlenToma]

Problem Description

I have build an app base64string-package-maker to be able to decrypt packages so that I could use the package on other apps.

The problem is that When I build publish/create app Package with release as a target I only get blank app.

That mean when I run Install.ps1 the app gets installed but there is no js included what so ever.

I think that the app boundle is not included somehow or maybe something else.

I do not get Any exception or error, So I have no Idea what is happning.

Steps To Reproduce

1- create an app and then publish it with release
2- You will get a clean app without any js

OR

1- fork my app base64string-package-maker
2- publish it and see that there is no js included

Expected Results

The app should show the js components and run as normal.

Solved it by downgrading react-native to 0.67

[chrisglein]

The link to base64string-package-maker doesn't work, is it a private repo?
Is your app C# or C++?

Through validating the publish of React Native Gallery on 0.69 we know that bundling for C++ in release is good.
The end to end test app should be validating this with tests that run release with the bundle. @jonthysell can you validate that is being covered here?

[AlenToma]

I hade downgraded to 0.67.4 and it is working now so the repo work now and I changed it private.

The repo I create is cs with the latest react-native and latest react-native-windows.

So as long as you create one and publish it with a release, I am sure that you will get the same problem.

The only libraries I hade on top of react-native and react-native-windows are the following

    "crypto-js": "^3.1.9-1",
    "js-base64": "^3.7.2",
    "react-native-fs": "git+https://github.com/avmoroz/react-native-fs.git#dev",

[jonthysell]

I can repro this on 0.69. The bundle file is present in the appx package, investigating to see why it isn't loading when the app starts.

[jonthysell]

Confirmed that the bundle is seen and loaded from disk, still investigating.

[jonthysell]

Confirmed that this repros with new 69 C++ apps in release mode too.
