That is strange, is it a custom board? Any chances that you can reproduce this on the DK? so that I will attempt to reproduce it and help you debug it?

something wrong seems to be happening inside components\libraries\pwr_mgmt\nrf_pwr_mgmt.c:shutdown_process(). Can you see if there are errors returned anywhere when this function is called after the softdevice is disabled?

I'm using `nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_STAY_IN_SYSOFF);` to shut down the MCU.

This should not have happened. Can you please post the code snippet on the logic of how you are going to sleep? Are you using softdevice API to go to sleep even after disabling the softdevice?
