index.android.bundle missing in APK after upgrading to RN 0.68

After upgrading our RN app to RN 0.68, we are getting errors with the release build:
FATAL EXCEPTION: create_react_context
Process: com.app, PID: 15057
java.lang.RuntimeException: Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release.
The app works fine in development, and was fine before upgrading. It is using Hermes, but not using the new Fabric architecture.
When building the APK and then looking into its content, we can see that the bundle is not copied. But it is correctly built in the intermediate artifacts:
$ ./gradlew assembleRelease

I am suspecting that there is a missing build step and it is not copied to the final directory, but I am not familiar enough with Gradle or RN's build process to check this.
Do you have any idea of what can cause this, or where to look at to troubleshoot this?

Found it after comparing the build files with a brand new RN app!
I had
classpath("com.android.tools.build:gradle:7.1.2")
in android/build.gradle
But with RN 0.68, you need to depend exactly on version 7.0.4, otherwise the JS bundle is not copied into the final APK.
The release APK is now working after switching to
classpath("com.android.tools.build:gradle:7.0.4")

How can i build Miscord on aarch64?

I am trying to build Miscord from source
(https://github.com/miscord/miscord/archive/v5.0.4.tar.gz)
on aarch64(my phone). root#kali is a Chroot enviorment on my phone. I have tested other distros((debian&ubuntu)aarch64) but no success as well. On PC amd64 starts no problem.
This is how i tried to start it. Posted the log at the bottom.
Thanks in advance!
npm was installed with
apt get install npm
Here is the commands i run:

Miscord should not be run with root permissions.
If running without sudo doesn't work, you can either fix your permission problems or change where npm stores global packages by putting ~/npm/bin in your PATH and running:
npm config set prefix ~/npm
See: https://github.com/sindresorhus/guides/blob/master/npm-global-without-sudo.md
If you really need to run Miscord with sudo, add parameter --runningWithSudoIsDangerous.

react native app crash after splash screen

I am new to React Native. I am created a new blank project in Expo XDE and when I'm trying to run it on my Android device every time it crash after splash screen. It's just a simple blank app.
There is no logs or errors. Expo app just return to first page.
Device: Android 7
XDE: Expo version 2.21.00

Which OS? Mac, Win, or Linux? If you're on Linux, did you open the XDE client using this command?
On Linux, open with chmod a+x xde*.AppImage and ./xde*.AppImage
Regardless of your OS, are you sure you have...
the latest version of node installed?
the latest version of watchman installed?
A shot in the dark, but once you've updated the above, I would start a new project and try again.
UPDATE: Looking more closely at your logs, I can see you're on Windows since the paths are "C:\...", so ignore the linux comment above. I still think your environment isn't setup correctly though. Reinstalling node and/or watchman may help (most likely node). You might also try installing yarn and see if that makes a difference. Sometimes it does for me.

ionic build error code 137

I am trying to build my app for android. It built fine for the first time but there were some typos in first so i edited the html and now i am trying to build the app. It is giving an error with exit status 137. the nodejs is latest so is the npm. I have checked the memory approx 700mb available.
New to ionic so now i cannot figure out the mistake.
Also rebuilded the node-sass. Nothing is working.
it takes too much time after sass started and then gets killed automatically.
