WebGL Runtime error: "RuntimeError: indirect call to null"?

Hello all.

(Sorry, I’m not sure which forum to post this on, so I’m posting it here)

I’m trying to publish a game on Gamejolt, but I get the runtime error mentioned in the title: “RuntimeError: indirect call to null”.

Here is the screenshot of the full error message:

Here are my Settings for Unity Build and Player:


Link to the game: Playing Game - Game Jolt

There are no runtime errors in my game, so it’s something with the WebGL configuration I guess, but I can’t figure it out. I searched the web for this particular error, but couldn’t find a solution. Unity 2019 haven’t had these kinda troubles with WebGL, and I have published games with it. It’s only after the upgrade to 2021 that I’m having issues with WebGL, and PC builds have no issues whatsoever.

Any suggestions on how to fix the error please?

Thanks for any input…

Did you ever get a solution to this? I’m also getting a “call_indirect to a null table” error. Only on iOS, Android and Windows run my WebGL app perfectly. Apple is driving me nuts as I MUST get my WebGL to work on iOS as well…
