WebGL not building

Hi, I was wondering if anyone ever had the same problem or have a solution for the problem that I have when Building a WebGL app from Unity.

It took me two whole hours to build the app only to result in failure

Code (CSharp):

1. Building Library\Bee\artifacts\WebGL\build\debug_WebGL_wasm\build.js failed with output:
2. C:\Program Files\Unity\Hub\Editor\2021.2.17f1\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\Emscripten\emscripten\tools\acorn-optimizer.js:1845

And also there's this error:

Code (CSharp):

6. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

And lastly this error:

I am experiencing this also. Any updates?

 

Same here no Solution

 

I finally managed to get it work, but for me it's because my files are too large. I don't know about you guys tho.
