Hi Steffen,
Which board are you using? KEA General Purpose Evaluation Board or your custom board?
Whether the NMI pin has an external pull-up resistor?
Is your program in Flash or RAM?
Have you test the S32DS Examples Projects of KEA128 or FRDM-KEAZ Freedom Evaluation Board – QSP ?
Will these projects also encounter this problem?

Also, please pay attention to the selection of Libraries support, do not choose those with Debugger Console.

Best Regards,
Robin
