Unity WebGL Development Build returns errors only once FMOD is added

Marktadros22 · October 17, 2020, 2:19pm

I’ve tested this with a completely new project and the issue still pertains.
Unity Development Build for WebGL returns these 3 errors every time I try and build it only once adding FMOD. The WebGL build works perfectly fine otherwise, all code is doublechecked and I tried deleting everything and building it on Desktop, as well as changing its name to simple characters, all to no avail.
I’m using Unity 2019.4.12f1 and FMOD 2.01. I’ve tried it with different FMOD versions but not with different Unity versions as I need this one explicitly.
The build seems to stop at “Compile WebAssembly module…”.

The errors are :
Failed running "D:/Unity/2019.4.12f1/Editor/Data/PlaybackEngines/WebGLSupport/BuildTools/Emscripten_Win/python/2.7.5.3_64bit\python.exe
Exception: Failed building WebGL Player.

Are you able to share more of the console log at all?
2.01.04 fixed a couple of issues with HTML5 if you haven’t already tried that version.

Hi Cameron,
Thanks for getting back to me. I tried with 2.01.04 with a completely new project and it still didn’t work. Once again stuck on “Compile WebAssembly module” before returning the errors. This is still Unity 2019.4.12f1, and again works completely fine with Development Build turned off. Here are the full error logs:

Thanks for the information, we have found the issue that is causing this and fixed it for the next release (which is due to be out at the beginning of next month).
