Does touchscreen feature work in other applications?
I appreciate you for providing details about the issue and your efforts towards resolving it.
This issue may occur due to corrupt app or game files and settings. Touch screen may not work properly due to corrupt installed drivers.
I would suggest you to run app troubleshooter and check the issue.
