This should be moved to the Android Public Tracker > Text component, but I don't have permissions so I'm redirecting to the appropriate owner.

So after updating to 1.4.1 and all deps too, the crash was a little different see below.

The repro for that one is easy

1. create a new app from AS 7.1 RC 1
2. update deps to (Appcompat 1.4.1/Material 1.5.0/Constraintlayout 2.1.3)
3. Add 2 textViews

    <TextView
        android:id="@+id/text1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/text2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/text1" />```

4. In onCreate:

        val t1 = findViewById<TextView>(R.id.text1)
        val t2 = findViewById<TextView>(R.id.text2)

        val charBuffer1 = CharArrayBuffer("AAA".toCharArray())
        charBuffer1.sizeCopied = 3
        val charBuffer2 = CharArrayBuffer("AAA".toCharArray())
        charBuffer2.sizeCopied = 3

        t1.setText(charBuffer1.data, 0, charBuffer1.sizeCopied)
        t2.setText(charBuffer2.data, 0, charBuffer2.sizeCopied)

5. Run see the texts updated then crash with the following. (Tested on P6 Pro Android 12)
