Build WEBGL Error in Unity 2019.3.3f1

Hi everyone I've been dealing with this error for one day, reading all the forums, answers to the base problem and versions that are supossed to be okey on build. I uninstalled all versions that i had, I've tried with some other versions and I finally give up on this pursuit. Please help me with this problem.

This is the error that I have:
