You have two different versions of the RAK3112 pin variants definitions, which are not in sync:
examples/RAK3112/IDE-Patches/PlatformIO/rakwireless/variants/rak3112/pins_arduino.h
PlatformIO/RAK_PATCH_V2/rakwireless/variants/rak3112/pins_arduino.h
The first one is misleading and would not work with RAK1920 as there would be no way to turn on the 3V3_S power, because WB_IO2 is defined to be the wrong GPIO. This wouldn't be a problem if the documentation [1] [2] did not specifically point to the first path each time it mentions the "Github repo".
