Hello Tanu,
The latest version of Make it Native 9 available in the Play Store is only compatible with Mx9.24+.
If you have an older version of MiN 9, you should upgrade to the latest version.
The opposite is true: if you have the newest MiN9 installed in your device, you must downgrade MiN9 to the compatible version if your project is < 9.24:

The docs used to have a link to the older version:

but unfortunately it’s not working anymore.
Finally, the best option is to build a custom developer launcher for your project and not use MiN anymore:
You'll need a similar procedure to generate the AAB to publish to stores, so it's worth learning how to do that anyway.
