Indeed, the problem was in this sign "?" in FREERTOS-STM32F4xx_Configs.xml ....Probably someone joked in ST :face_with_tears_of_joy:. Now appeared an initialization of tasks, semaphores, mutexes after calling the osKernelInitialize() function. Thanks...

Having the same problem after updating STM32CubeIDE. I think this is a bug in STM32CubeMX made by ST developers.
