Phaser 3.18.1 ie11 security error

When I open my game in ie11 I see the following:

Does anyone know what this error is saying is the problem?

this is a DOMException. More specifically, a Security Error (The operation is insecure.)

I don’t really use ie11, but if I were in your shoes I would:

  1. isolate the code that generates this error. Try commenting out Scenes and things you do in the game until you no longer see this error.
    If you are using git, use git bisect to find the commit that breaks your game.

  2. clear out your cache, cookies, etc

  3. show us your code
