WebGL: UnusedBytecodeStripper2.exe did not run properly

crutch12

Hello! I try to build project which contains Photon Unity Networking (last version from Asset Store) in WebGL.
But there are 3 same errors:
Error building Player: Exception: C:\Program Files\Unity\Editor\Data\Tools/UnusedByteCodeStripper2/UnusedBytecodeStripper2.exe did not run properly!

So, what can I do? I tried build own project with photon - same error. I tried build New project + photon (scene from Demos) - same error. I tried turn on/off WebGL in list of plugins websocket-sharp.dll and WebSocket.dll - same error. I tried turn on/off "Run in background" and "Strip engine code" in Player Settings - same error!

And when I try just play it in editor: if in PhotonServerSettings I choose Hosting:PhotonCloud - it works (DOESN'T BUILD, JUST WORKS IN EDITOR) but with high ping (~300); if I choose Hosting:SelfHosted - it even doesn't work in editor and gives error (Protocol:Tcp or Upd - doesn't matter - error):
UriFormatException: URI scheme must start with a letter and must consist of one of alphabet, digits, '+', '-' or '.' character.

All these problems only with WebGL!
(I use last version of Unity)
Help!

The first error can be solved by not using .NET subset stripping level

The second by putting the full url (with the wss protocol), like wss://yourDomainOrIP
