Applepencil does not work (only when turn on Minecraft)

Apple Pencil does not respond when Minecraft is running.
Previously available.
Apple Pencil does not respond only to Minecraft when the iPad is powered off and turned on too.
I don't know what the problem is.(This is not a Bluetooth issue.)

When creating a new world, the keyboard that appears at the bottom to set the title is a response, and when I lower the keyboard from the window and return to the application, the Apple Pencil is not available again.
Please let me know if there is a solution. Thank you.
