Program runs under Keil uVision but not under STM32CubeIDE - c

Question

I have a small program running on stm32wb55. It tests the TIM2 timer with a delay function called wait_us(). The program runs correctly when I compile it with Keil uVision 5, but when I compile it with STM32CubeIDE it gets stuck in the function get_us(). Is there a bug in STM32CubeIDE?
