When activeted SDRAM, touch part dont work and screen is frezee

I am using below development tools

MCU: STM32H7B3IIT6

IDE: STM32CubeIDE Version: 1.8.0

GUI: TouchGFX Version: 4.18.1

SDRAM: IS45S16800F-7CTLA1-TR

When activeted SDRAM, touch part dont work and screen is frezee, FMC settings are as follows.
