Having the same issue on installing Beta 4. Creating new admin user did not resolve the problem.

You can open it again by right click (option click) your .swiftpm file, click "Open with" and choose Xcode from the menu.

I am having the same issue too: https://developer.apple.com/forums/thread/703935. I have reached out to the team through email and will update here if I got any responses.

Update: for anyone who had the same issue, I got an email from the team and this should have been resolved now.

I am having the same issue when trying it on an iPhone 13 mini. Not sure if it's hardware restrictions.

@jamesboo I have found a fix. On line 53 of CameraViewController.swift, you can try to change the device type to something else like .builtInDualWideCamera.
