Yes, that's exactly the feature the game currently requires. And to use that, the cross origin isolation feature must be supported by your browser.The app seems not to.

As soon as I can uncheck the shared array buffer it is going to work on the app. Until then I can't do much about it.

Godot4 games currently still require a feature called "shared array buffer" to run in browsers. That feature depends on cross origin isolation, which seems not to work on the app. As of now there is nothing I can do to change that, however, with a future release of the engine this will change. I'll update the game when that happens, but I'm afraid until then you're best off using a chrome based browser to run it.
