Yesterday i was making some builds for webgl, and had some issues with FMOD, an audio plugin.
I made some dev builds to see what the error was exactly, but after like 3 dev builds unity refused to build to WebGL, and always gives me build failed.
I get the same errors with unity version 2019.2.13f1 and unity version 2019.3.13f1
These are the errors:
Failed running "C:/Program Files/Unity/Hub/Editor/2019.3.13f1/Editor/Data/PlaybackEngines/WebGLSupport\BuildTools\Emscripten_Win\python\2.7.5.3_64bit\python.exe" -E "C:/Program Files/Unity/Hub/Editor/2019.3.13f1/Editor/Data/PlaybackEngines/WebGLSupport\BuildTools\Emscripten\emcc" @"D:\slashy ninja update version\slashy ninja\Assets\..\Temp\emcc_arguments.resp"
stdout:

I saw other people having similar problems, and tried all kinds of solutions:
reimporting all assets, saving build in another place, running unity as admin, modifying a file called “emscripten.config” (stack_size).
I even duplicated my project and build it from unity 2019.3.13f1
I got no idea what to do next, since the errors are a bit too advanced for me.
