Can't program LoRa board

Wireless & IoT LoRa (Long Range)
1

Board: WRT-14916

Arduino Version: 1.8.13

Mac OSX 11.0.1

I can select the board from the board menu and the board shows up under port at the Pro RF board. When I try to program the board, I get the following error:

java.io.IOException: Cannot run program "{runtime.tools.bossac-1.7.0-arduino3.path}/bossac": error=2, No such file or directory

An error occurred while uploading the sketch

It looks like the build system is trying to use the 1.7 version of the Arduino tools instead of 1.8. Any idea how to fix this?

Thanks,

Rob

I was able to solve this by uninstalling Arduino and the Arduino Libraries and re-installing them.
