That fixed it! Great, thanks for the super fast reply :)

For anyone who has the same issues, this is the new main.c file:

Hi,

It looks like you might have run into NCSDK-10106.

Can you try to enable the modem library by enabling CONFIG_NRF_MODEM_LIB and calling nrf_modem_lib_init()?

Best regards,

Didrik
