Multi Scenes with videoplayer bug Cannot use 'in' operator to search for 'requestVideoFrameCallback"

In the multi scene switch example I have tried using my own scenes and two have a video player in them, sometimes when changing scenes I get this error and the next scene fails to load.

engine_context.js?v=3450b8d8:897 Frame #176
 TypeError: Cannot use 'in' operator to search for 'requestVideoFrameCallback' in null

Do you think you could report this with the bugreporter?

I’m just checking it isn’t because I use this script to reference the video textures on an alpha material in the scene
AlphaVideo.ts

I’ll report it if I see it happen again - for now I added this line to make the referenced texture null on destroy and haven’t seen this since

  onDestroy() {
    this.mainMaterial.alphaMap = null;
  }
}

is this script in one of the sub-scenes or in the scene with the SceneSwitcher (the parent scene) - because then it would make sense (on switching the scene the old scene gets unloaded so the texture would be disposed)

Its on the sub scenes, I think I fixed this issue now
