LPUART LL example - Rx not working

Hy everybody,

I have a Nucleo 144-L496ZG board and I test the STM32Cube_FW_L4_V1.13.0 Examples_LL\LPUART\LPUART_WakeupFromStop2 example with IAR. The Tx is working (I see it on the PC's Realterm /TeraTerm) but the Rx doesn't. Even if I do not enter the Stop2 mode, the breakpoint in the 'void LPUART_CharReception_Callback(void)' function is not reached when I send something from the PC's terminal application ( I see the PC transmition on the scope). Other examples, like Standby and RTC are working fine.
