Damaged Crystal pins STM32F407

Hello friends,


I have a few STM32F407ZET6 that do not work, and the reason for not working is getting stuck in the HSE Init function.

I will change the capacitor and Crystal, but it will not be right
when I change my Micro everything is fine

Crystal = 8mhz
capacitor= 20pf

Where the CPU catches

Code:
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    _Error_Handler(__FILE__, __LINE__);
  }

I feel oscillator pins are damaged
Is there a protective circuit for it?
 

Protection from what? Meteors? What damaged the micro originally?The oscillator circuit is going to be sensitive to anything you might attach there(additional capacitance/inductance).
