Infinite loop in HAL_RCC_GetSysClockFreq() in HAL_RCC_ClockConfig() onNucleo STM32F446RE

I am using the latest System Workbench on Nucleo to set up for experiments.

My code is as follows:

#define SYS_CLOCK_FREQ_50_MHZ 50
 
int main(void)
{
 
	HAL_Init();
 
 
	SystemClock_Config_HSE(SYS_CLOCK_FREQ_50_MHZ);
 
	GPIO_Init();
 
	UART2_Init();
 
	TIMER2_Init();
...

The SystemClock_Config_HSE(...) is as follows:

void SystemClock_Config_HSE(uint8_t clock_freq)
{
	RCC_OscInitTypeDef Osc_Init;
	RCC_ClkInitTypeDef Clock_Init;
 uint8_t flash_latency=0;
 
	Osc_Init.OscillatorType = RCC_OSCILLATORTYPE_HSE | RCC_OSCILLATORTYPE_LSE | RCC_OSCILLATORTYPE_HSI ;
	Osc_Init.HSEState = RCC_HSE_ON;
	Osc_Init.LSEState = RCC_LSE_ON;
	Osc_Init.HSIState = RCC_HSI_ON;
	Osc_Init.PLL.PLLState = RCC_PLL_ON;
	Osc_Init.PLL.PLLSource = RCC_PLLSOURCE_HSE;
 
	switch(clock_freq)
	 {
	 case SYS_CLOCK_FREQ_50_MHZ:
		 Osc_Init.PLL.PLLM = 4;
		 Osc_Init.PLL.PLLN = 50;
		 Osc_Init.PLL.PLLP = RCC_PLLP_DIV2;
		 Osc_Init.PLL.PLLQ = 2;
		 Osc_Init.PLL.PLLR = 2;
		 Clock_Init.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
	 |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
		 Clock_Init.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
		 Clock_Init.AHBCLKDivider = RCC_SYSCLK_DIV1;
		 Clock_Init.APB1CLKDivider = RCC_HCLK_DIV2;
		 Clock_Init.APB2CLKDivider = RCC_HCLK_DIV1;
 flash_latency = 1;
	 break;
 
	 case SYS_CLOCK_FREQ_84_MHZ:
		<< These cases are not relevant here>>
	 default:
	 return ;
	 }
 
		if (HAL_RCC_OscConfig(&Osc_Init) != HAL_OK)
	{
			Error_handler();
	}
 
 
 
	if (HAL_RCC_ClockConfig(&Clock_Init, flash_latency) != HAL_OK)
	{
		Error_handler();
	}
 
 
	/*Configure the systick timer interrupt frequency (for every 1 ms) */
	uint32_t hclk_freq = HAL_RCC_GetHCLKFreq();
	HAL_SYSTICK_Config(hclk_freq/1000);
 
	/**Configure the Systick
	*/
	HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);
 
	/* SysTick_IRQn interrupt configuration */
	HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);
 
 }

Now when I build, load the program and try running it in the debugger I see that it is stuck in an infinite loop in HAL_RCC_ClockConfig(...). Why did it go into the WWDG_IRQHandler()?

This EXACT same code runs fine under Keil MDK.

The version of System Workbench I am using is:

Any ideas? I tried it with a previous version of System Workbench and I have the same issue.

Thank you
