Super ContributorKDB articles say this was a bug fixed ages ago: https://www.intel.com/content/www/us/en/support/programmable/articles/000074027.html
So it's weird that you're running into it.
Obviously your board is built so you have to use that pin, but can you try moving the LED output location, compile, then move it back and compile again?
You could also try deleting your db and incremental_db folders to do a fresh compile from scratch.
