stm32H743ZI TouchGFX FrontendHeap HardFault

I have an Error using a Custom Board with a STM32H743ZI controller.

First a want to use the internal Flash and RAM_D1 for the TouchGFX App but i always get a Hardfault on Line
FrontendHeap& heap=FrontendHeap::getInstance();

__HAL_RCC_CRC_CLK_ENABLE(); is executed
my Toolchain is up to date

any ideas?
