WebGL Build failed

Unity Engine

Hi! I am trying to build and publish a karting microgame but everytime I try to build, it fails. I am using Windows 10 and Unity 2019.4.23f1 (personal). I tried to build for Windows and for WebGL, but it never works…
Here are the error reports for WebGL:

Same here. I am following the Karting tutorial. Everything is good until the publish lesson. It starts to build, then stops and the build folder is empty. No warning/message as to what’s failing/why. I think I will reboot and try again. (I wouldn’t even know where to find all the error messages you are getting. My build just ends with no failure message).
