tfm_ns_fault_handler_callback is called when booting

[Replay]

Hi,

I have a problem where tfm_ns_fault_handler_callback is called when booting the system.

This results in arm_fault and k_sys_fatal_error_handler is called. The reason is 41.

I have upgraded to SDK v2.6.1

Custom board based on nrf9160-SIP

The project is based on a azure iot hub example.

This is the error log:
