USART2 works but other USARTS don't work. (STM32F446RE)

Hello,

I am struggling to use multiple USARTs. I tested that USART2 works fine but I cannot get USART1 and USART3 to work.

If I can't use multiple USARTs at the same time, I would like to use only USART3. However, USART3 does not work. Do I need to change settings on the Windows to use different USART?

I am using STM32F446 nucleo board and using Putty to see serial port on windows.

Any help would be very appreciated!

Thank you

void SendInitString(void)
{
	uint8_t Test3[] = "Hello World 33 !!!\r\n"; //Data to send
	HAL_UART_Transmit(&huart3,Test3,sizeof(Test3),10);// Sending in normal mode
 
	uint8_t Test2[] = "Hello World 22 !!!\r\n"; //Data to send
	HAL_UART_Transmit(&huart2,Test2,sizeof(Test2),10);// Sending in normal mode
 
	uint8_t Test1[] = "Hello World 11 !!!\r\n"; //Data to send
	HAL_UART_Transmit(&huart1,Test1,sizeof(Test1),10);// Sending in normal mode
	HAL_Delay(1000);
