Android-After rebooting, launching one application from another application does not open the app

Question

I am experiencing an issue with opening an app on Android 13. When I use the following code to launch another application, it works fine after rebooting the tablet.

            val intent = Intent("android.intent.action.MAIN")
            intent.putExtra("fromIntent", true)
            intent.setPackage("com.example.myapp")
            intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
            intent.putExtra(Constants.DEVICE_TYPE_ID, deviceType)
            intent.addCategory("android.intent.category.LAUNCHER")
            intent.component = ComponentName("com.example.myapp", "com.example.myapp.MainActivity")
            startActivity(intent)
            finishAffinity()

However, if I use a different code to launch another application, it doesn't work after a tablet reboot. I am expecting the below code working.

        val intent = packageManager.getLaunchIntentForPackage("com.example.myapp")
        if (intent != null) {
            intent.putExtra("fromIntent", true)
            intent.setPackage("com.example.myapp")
            intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
            intent.putExtra(Constants.DEVICE_TYPE_ID, deviceType)
            intent.addCategory("android.intent.category.LAUNCHER")
            intent.component = ComponentName("com.example.myapp", "com.example.myapp.MainActivity")
            startActivity(intent)
            finishAffinity()
        } else {
            Utils.showErrorLog(TAG, "Null Intent")
        }

In normal cases, it's working fine. However, the issue was faced after restarting the tablet. Can you please provide a solution why the above code is not working?
