CaptureSample app fails to save files

I downloaded and built this app for capturing images that can be used to generate a USDZ 3D model file. But it doesn't work for me. I can take the photos and see them in the app, but there are not saved. Here are some of the log messages produced by the app. Note the last line.

  • Creating capture path: "file:///var/mobile/Containers/Data/Application/40A7C69A-DE34-43B8-A1DF-D3BB87D5C23E/Documents/Captures/Jan%2029,%202023%20at%201:33:54%20PM/"
