Hi @Nina,
Thank you for your help. But, following your tips, solving the warnings and uninstalling unused packages didn’t solve the issue.
I also tried the ‘Build and Run’ to WebGL in the Number Wizard Project, with the same erros.
It may be related with this error message - as you see, my user account has non-english characters:
Response file: C:\Users\Jo�o Coelho\AppData\Local\Temp\_1483805527\response.rsp
il2cpp.exe didn't catch exception: Unity.IL2CPP.Building.BuilderFailedException: "C:\Program Files\Unity\Hub\Editor\2018.4.26f1\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\Emscripten_Win\python\2.7.5.3_64bit\python.exe"
I don’t know. I’am tired of looking for a solution and it’s not so important on this phase. So I’ am moving on to next lecture.
Anyway, thank your for your help!
