WebGL I have this message :
DirectoryNotFoundException: Could not find a part of the path ‘/home/~/Unity/Hub/Editor/2020.2.0a12/Editor/Data/PlaybackEngines/WebGLSupport/BuildTools/lib/modules’

there is no folder lib there. But i do not know where it should be and how can I fix the path
Thanks

Hi did not fix the issue but from another forum they advice me to download and use a non-alpha build.
It works great.
So this thread can be closed
