Are you using Graphene with the default keyboard or Florisboard? That combination is the issue. If you change it to Anysoft, Unepected Keyaboard do Gboard it won't crash anymore. 

 I'm using Samsung android. The keyboard is Florisboard.

Lemme check as you suggested. 

Thanks @Vitor Pamplona, for your precious time.

I changed the keyboard to Gboard. And it works. 🫂❤️
