I must have done something wrong. My cube continued spinning when the inscription appeared.

Windows and Vivaldi: runs fine.
iOS (Vivaldi and Safari, which both use the same browser engine): Freezes once the text appears.

Yeah, I have Win 11 WS. Could it be the OS?

But the inscription appears in the corner for me.

Tested also on my Iphone. It seems ALL apple devices have the same issue.

This is very annoying bc i can’t have ANY ui in my game.

And the game still runs in the background, the image of the 1st frame after the canvasLayer is shown is frozen, until a scene is changed.

I think the Web export has had problems with MacOS for a long time. I remember not being able to run Godot web games on my macbook, but that was a while back.

https://docs.godotengine.org/en/stable/tutorials/export/exporting_for_web.html

If I interpret the documents, it has had issues with multi-threated exports, but should work better if exported single-threaded instead. Stated from the docks:

The single-threaded export works very well on macOS and iOS too, where it always had compatibility issues with multiple threads exports.

So what happens if you export using single thread instead?

Here's also a list of known web export bugs. Maybe there's something there that could be related to you?

When I opened the test project on iOS there was a "this is not compatible with your system" (or something like that) warning below the game.
