Unable to use NanoPB with Sidewalk

[vawkes]

Hello, I am trying to use the subghz template in ncs 2.5.2 but I am running into an issue when enabling NanoPB. When enabling NanoPB with CONFIG_NANOPB=y the application faults when connecting to BLE to register on the network. If I am already registered on the network the application runs fine but it seems there is something in the BLE registration that is causing a fault with NanoPB.
