Is this in your main level?
I have a quick fix theory that I have yet to test. I am thinking of loading a blank level as the main level and put loading screens and then a delay to load the main menu, as it only happens on the first level, I believe this may “fix” it, although the loading screen level may have the error, its not as much of an issue. This is why i wonder, is this happening for you in game, or on the first initial level?
