It seems it is the compilation of the shaders which takes time.

You should try to load everything you need at start and wait for the scene to be ready (scene.executeWhenReady) before starting the experience. Try also to use WebGL instead of WebGPU, as shader compilation is slower in WebGPU and not asynchronous yet.

I resolve the ploblem via restart computer. I think it could be some other timing task in the OS that is blocking the broswer or GPU runing.
