Problem with the UpdateEvent

[H_Manager20]

Hi everyone, I'm new to STM32. I'm trying to use the STM32C011x4's internal temperature sensor.

I'm doing the same as the website below:
https://deepbluembedded.com/stm32-internal-temperature-sensor-reading-example/#:~:text=The%20STM32%20microcontrollers%20have%20an,ambient%20temperature%20sensor%20failure%20events.

But my code doesn't go into the "if(UpdateEvent){" line. 

I inserted an LED to debug, but it doesn't turn on.

Can someone help me??? follow the code below

I thank the attention
