Building to WebGL failing, failed running il2cpp.exe

Hi everyone,

I just installed Unity and I'm trying to export small games to WebGL just to test stuff, building to .exe is working but not WebGL, here's are the errors I'm getting, anyone knows whats going on? I read every thread related to il2cpp.exe but didn't find a solution. Thanks in advance.
