"Experience.rcproject" file missing from new RealityKit project in Xcode 15.0 beta 3 (15A5195k)

I create an Augmented Reality App for iOS, selecting the options "Storyboard", "Swift", and "RealityKit". The tutorial I'm following seems to think there should be a file "Experience.rcproject" containing a default scene with a cube, but this file is missing.

Any advice on how to find or create a copy of this file, so I can continue the tutorial?

Sorry, I meant to ask in the original post: is anyone else seeing this problem, or is there something wrong with my setup?

apparently an issue with the xcode beta that is missing the file. just used the xcode 14.3.1 to generate the same project and there is the experience file. you can copy it to the project folder of the beta if you like
