Sample and Application build errors

Operating System

Windows 11

What happened ?

hello_world sample compiles and flashes, but I am finding build issues with the sample builds.
Goal is to provision TLS Certificates for a build that connects to AWS IoT Core, successfully tested on nrf9161-dk.
Provisioning certificates via AT commands with modem_shell Serial was not successful (ERROR).
Have tested with sdk-nrf v2.9.1 and v3.1.0.

How to reproduce ?

Follow getting started, then build sample.
