I loaded the library but on compile it says file not found... halp!
GitHub - rstephan/ArtnetWifi: Arduino library for Art-Net (artnet) over WiFi, send and receive DMX data. Runs on ESP8266, ESP32, Pi Pico W, WiFi101 and WiFiNINA devices. the library i am trying to use
There have been several reports of things like this in the Arduino Web Editor. I recommend using the real Arduino IDE instead. You can download it for free from here:

Go with Pert's suggestion and get the regular desktop IDE.
