WebGL builds in version 2020.2.1f1 are not working?

Question

As the title suggests, I've previously built a game for WebGL in a 2019 version and it was alright. I've updated to the latest version of 2020 and it simply seems that the build operation for WebGL in this version is screwed up..

First I get an error on the web page that says: WebGL builds are not supported on mobile devices.

But it's on a browser on my computer.. It's not from my smart phone...

Secondly I get this warning: The script from “http://mygame.me/Build/MyGame%20Build.framework.js.gz” was loaded even though its MIME type (“application/x-gzip”) is not a valid JavaScript MIME type.

At last, I get 2 console errors:

Uncaught SyntaxError: illegal character U+001F

Uncaught ReferenceError: unityFramework is not defined.

What can I do to solve this?

Is this a known issue?

Is there a workaround for this?

Am I really restricted to build WebGL games only from 2019 versions?

Answer 1

I also cannot run my game build with 2020.2.1f1

I have this warning:

 WebGL.framework.js:2 WebGL: INVALID_ENUM: getInternalformatParameter: invalid internalformat
 _glGetInternalformativ @ WebGL.framework.js:2

Followed by

 Exception at: 
 Error
     at jsStackTrace (http://localhost:52008/Build/WebGL.framework.js:2:16493)
     at stackTrace (http://localhost:52008/Build/WebGL.framework.js:2:16664)
     at http://localhost:52008/Build/WebGL.framework.js:2:3544
     at http://localhost:52008/Build/WebGL.wasm:wasm-function[102515]:0x1f56d07
     ... a tone of unreadable stacktrace

And two errors:

 exception thrown: undefined - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch. WebGL.loader.js:1:4256
 
 Uncaught undefined - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch. WebGL.framework.js.gz:2:563707

Only way I found after a day trying, was enabling all debug options, full stacktrace and everything. Ok it showed some warnings I've fixed, but still not playable in release, and unplayable in this debug condition...

EDIT: checking "Data caching" & "Decompression Fallback", and unchecking "Prebake Collision Meshes" & "Optimize Mesh Data" made my build run !

I've read that thread, though I have no idea what is that .htaccess..

Is that a file? If so, I don't find it.. In the build folder there is only 4 files, 3 of which are zipped.
