AudioListener makes WebGL crash (?!)

Weird problem, took me days to narrow it down.

• The game works fine in Windows Build.

• The game crashes in WebGL build (the web page crashes before we can even see the Unity Splash Screen).

• When I remove the AudioListener on the camera... the WebGL build works fine. (o_O)

• If the entire Unity Audio is disabled, or if the GameObject containing the AudioListener is disabled... it crashes anyway, as long as the AudioListener is present.

• The problem is the same regardless of the browser or the computer I use (tried several).

I can't figure out why this is happening. I'm trying to solve this issue for weeks now...

Here are browser console logs on both cases.

I swear the ONLY thing changing between both is the presence of an AudioListener in the scene...

CRASH NO CRASH
