This is okay in other versions of ndroid but this error occurs in my android version 8 (Oreo) Samsung Experience 9.0.
Every time when I try to edit some existing data inside val lyricsEditor = view.findViewById<EditText>(R.id.lyrics_editor) , it crashes giving the logcat report as below.
I Tried by changing the typecast as val lyricsEditor = view.findViewById<TextInputEditText>(R.id.lyrics_editor)
but the problem is same as before.
This okay when I start a new editor. But the problem occurs when I try to edit existing data
I couldn't figure out any issues. Please help me.

I have done some researches from your provided exception log, that is a known bug for Android 8.0.
WordPress for Android had also encountered similar issue on Android 8.0 or 8.1 before.
There is a version fix related to that:
Fix DynamicLayout block index calculation after edit
DynamicLayout made wrong adjustments to the block indices set to be redrawn. Every indice after the first change was being added the diff count in the blocks. However this meant when there are 2 deletes and an index as 1, it would become -1 (wrong array index). The change should be applied to indices outside of [firstBlock, lastBlock].
And that's only available from Android 9 onwards.
And one suggested fix provided, is to disable hardware acceleration on the targeted view.
In code:
lyricsEditor.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
Or in XML:
<com.google.android.material.textfield.TextInputEditText
android:id="@+id/lyrics_editor"
style="@style/lyricsTvStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/square_edittext"
android:textColor="@color/blue"
android:layerType="software" />
