LPUART RX callback doesn't work

I try to use UART Communication together with an RS-485 IC (SN65HVD72DGKR).

Sending Text to an PC work correctly.


But I'm not able to receive some Text from the PC.

I checked out the lpuart example and also this topic in community: S32k uart RX interrupt handler problem 


But the callback function never gets called.

Even if I take out the RS485 Transceiver and connect RX and TX to a loopback, the Callback never gets called.

I use LPUART component from Processor Expert (see attached project).


What could be wrong here?


Thanky for any hints.
