xcode - RealityKit - Internal errors cause 2 seconds delay to startup

Question

I have a Swift RealityKit project, when I load the scene, I get a delay where Xcode spits out the following messages, which aren't related to any code I have written.

My app works fine, apart from the 2ish seconds that Xcode is complaining about these unknown things.

Can anyone shed any light on what I might have turned on that is causing this? I just need to kill whatever is delaying my startup

I had a similar trouble, and the problem was in my model. My solution was to change my model to a valid .usdz file. You can find some template models in here to check if it works https://developer.apple.com/augmented-reality/quick-look/
