DAVE 4.1.2 and CAN_NODE 4.1.6

Hello
I like to try a very simple example with the latest DAVE and the CAN App.
I have instantiated the CAN App which results in the following App hierarchy
CAN_NODE_0
GLOBAL_CAN0
CLOCK_XMC4_0
main() is emtpty. Only DAVE_Init(); is called.
Debugging the example results in a endless loop within xmc_can.c function XMC_CAN_Enable()
It looks like CAN does not have a module clock and is not enabled and the controller stays in the following loop.

while (obj->CLC & CAN_CLC_DISS_Msk)
{
/*Do nothing*/
};

I managed already CAN communication with DAVE4.0 and the XMClib only.
What is missing in the simple CAN App example? Any hint for me?

Regards
Heinz
