Xiao nRF52840 Sense and FastLED compatibility

I have been struggling for so gosh dang long trying to get the FastLED library to work with the Xiao nRF52840 Sense. Whenever I try to run the library I get an error code that seems to point to the file clockless_arm_nrf52.h, and is unhappy with a pin. Full error message is here: In file included from c:\Users\x\Documents\Arduino\libraries\FastLED\src/FastLED - Pastebin.com. Help would be much appreciated!

Hi shmixer,
FastLED may not support the nRF52840 at all, but if you don’t care about FastLED, “Adafruit_NeoPixel” library is running on nRF52840.
Also, if you show your FastLED sketch, we might be able to give you some advice.
