Android Studio – Options Menu Periodically causes App to Crash and Closes Last Activity

Solution: So, after being stuck on this for quite a while, I finally discovered that the issue was because my activity was titled Menu. I guess this is a reserved word in some way or another and because of that, it would cause random crashes to occur when trying to start the intent Menu::class.java. I changed the name of the activity and everything works as expected now.

I have added an Options Menu to an app that I am working on which contains a "home" button. The button works most of the time but periodically it causes the app to crash when it’s clicked. It seems to happen after the button has already been clicked at least once and/or after the native back button has been pressed. Additionally, once the button is pressed, it seems to close the last activity. Clicking the back button after clicking the home button does not take me back to where I was. Below is my code for the toolbar.

// Creates toolbar
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    val menuInflater = menuInflater
    menuInflater.inflate(R.menu.home, menu)
    return true
}

// Listens to click of toolbar
override fun onOptionsItemSelected(item: MenuItem): Boolean {
    val id = item.itemId
    if (id == R.id.home) {
        val intent = Intent(this, Menu::class.java)
        startActivity(intent)
    }
    return super.onOptionsItemSelected(item)
}

Here’s the logcat:
