Reproduced on:
- Mac mini (M1, 2020) (macOS 12.0.1 and 12.4)

Could not reproduce on:
- MacBook Pro (M1 Max, 16-inch, 2021) (macOS 12.2)

Notes:
- Not every machine is capable of reproducing the issue and has only been observed on an M1 machine, see comments regarding additional information regarding the devices in the reproducible list
- If the "Automatically Sign" setting is unchecked, then checked again, then the Xcode fields will be correctly set.
- The "Automatically Sign" setting can also be found in Preferences > External Tools. It was noticed that while this was checked in the Project Settings, it was unchecked in Preferences. If it is checked in Preferences before step 3, then the Xcode fields will be correctly set.
