I had this issue and I solved it by calling .setJavaScriptExecutorFactory(HermesExecutorFactory()) on the object returned by ReactInstanceManager.builder(). This works if you’re using Hermes

@sanjeevyadavIT in your case, because you’ve overriding the ReactNativeHost, you can specify the HermesExecutorFactory() like this:

        object : ReactNativeHost(application) {
            ...
            override fun getJavaScriptExecutorFactory() = HermesExecutorFactory() // <-- override this and set.
        }

As mentioned, the problem is that you’re not creating a ReactInstanceManager correctly. That’s how the ReactNativeHost is doing it:

https://github.com/facebook/react-native/blob/6439baaca12f844b2192740bbaa5ee61edcba608/ReactAndroid/src/main/java/com/facebook/react/ReactNativeHost.java#L69-L84

You should either follow this pattern or use DefaultReactNativeHost as the template is doing which simplifies this setup for you

This worked for me also for those still facing issue on 0.71.2

reactInstanceManager = ReactInstanceManager.builder().setJavaScriptExecutorFactory(new HermesExecutorFactory()).setApplication(activity.getApplication())
                    .setCurrentActivity(activity).setBundleAssetName("index.android.bundle")
                    .setJSMainModulePath("index.android").addPackages(this.getPackages(_env.getValue()))
                    .setUseDeveloperSupport(BuildConfig.DEBUG).setInitialLifecycleState(LifecycleState.RESUMED).build();

This worked more me.
