[UE4.27] Touch Interface Setup shows empty in editor

I find my Touch Interface Setup shows empty in editor, but it works last week.
I have restart UE4 many times, or create a blank project. The problem still exists.
I have verify UE4 integrity and i think i dont modify any source code.
What should i do?Thanks for your advice!
