Working with STM32H743 and STM32CubeIDE 1.14.0.

Created a project with FreeRTOS and USB Device CDC.

When the program goes into the first vTaskDelay(1000) a hard crash occurs.

    The default stack size set by FreeRTOS is 128.

    This is too small when instantiating the USB Device driver.

    Once I increased the default size to 512, the program stopped crashing
