Not Working WebGL

I have a game called Cat Run, and I was trying to use the WebGL for the first time to publish it because i am to young to use real publishing and it keeps giving me these errors, Building C:\Users\14706\Downloads\TemplateData\style.css failed with output:

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Building C:\Users\14706\Downloads\ServiceWorker.js failed with output:

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Build completed with a result of ‘Failed’ in 40 seconds (39852 ms)
2 errors
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

can you please help I have no clue what to do and am getting frustrated, please respond quick I need it published before me youtube video.

downloads? odd place to build to… anyway, there is likely more to the error, if you cant see details in the console, check the unity logs for more hints…
