Can't build WebGL because of IL2CPP crash

Question

Hi, when I try to build my game for the WebGL platform I get an error message that says il2cpp.exe is not responding and in the Unity console I get t$$anonymous$$s:

I noticed a part where it says (translated to english):

  il2cpp.exe didn't catch exception: System.UnauthorizedAccessException: Access to path 'C:\Users\Public\Documents\Unity Projects\Peanut Factory\Assets\Plugins\Android\MainLibProj' denied.

I thought I should run Unity as admin (I'm on Windows 7) but the error is still there.

T$$anonymous$$s is likely a known issue with the Facebook SDK and Unity. The WebGL build process is in correctly trying to use an iOS native plugin from the Facebook SDK. We have a fix coming in a Unity patch release soon. In meantime, you should be able to disable the iOS native plugin in Facebook SDK for WebGL using the plugin inspector in Unity.

Where is the plugin browser? I am not able to find t$$anonymous$$s either.

I have no plugins, do I have to make them myself? I am also stuck on the IL2CPP part on building my game to WebGL.
