Hi @slowtoaccept. Thanks for your report.

Please do this:
When you encounter an error you'll see a button on the right side of the orange bar in the Arduino IDE "Copy error messages". Click that button. Paste the error in a message here using code fencing.

Using library LoRa_Node at version 1.0.1 in folder: E:\Documents\Arduino\libraries\LoRa_Node 

Using library MKRWAN_v2 at version 1.3.1 in folder: E:\Documents\Arduino\libraries\MKRWAN_v2

So this is a name collision between the MKRWAN library and the "LoRa Node" library (https://github.com/arduino-libraries/LoraNodeShield)

Regarding this:

Alternatives for config.h: [LoRa_Node@1.0.1]

ResolveLibrary(config.h)

  -> candidates: [LoRa_Node@1.0.1]

I don't see anything about config.h in the sketch or the MKRWAN_v2 library. So I guess you have modified the sketch and will be able to solve this by carefully copying the exact code this time.
