JAX v0.4.11 is required, so fixed by any of the following suggestions: https://developer.apple.com/forums/thread/731465?answerId=756330022#756330022 https://developer.apple.com/forums/thread/731465?answerId=756319022#756319022 (JAX v04.12 doesn't work with Metal. v0.4.13 requires a newer version of jaxlib)

(M1 Max running Sonoma 14.0 and Xcode Version 15.0 beta (15A5160n))

This is still happening to me in Xcode 13.1 and Xcode 13.2 RC. My current workaround is to use Mac Catalyst (Rosetta) instead of just Mac Catalyst. Not ideal, of course.

Thank you, I can confirm it's fixed in Xcode 13.2 beta 2.

As a workaround we are currently copying the receipt from an App Store version of the app into the compiled bundle generated by Xcode. The app launches this way, and we can debug everything (except possibly IAP/App Store features). The receipt is stored in directory _MASReceipt, located inside the app's Contents folder.

Thanks for taking a look! I submitted FB9588695 yesterday, and I just attached the full source of the Metal file.
