Can't build Universal or Apple Silicon Binaries on M1 Macbook

When packaging my game for debug or shipping builds, I receive the error

ERROR: Missing precompiled manifest for ‘Launch’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in Launch.build.cs to override.

When I go to the engine Launch.build.cs file and add the line above, nothing changes. I’ve been able to make the error go away when I change the build type to Intel. This issue persists on new projects, and occurs for me in both 4-26 and 4-27. I’d love to hear potential solutions, as I don’t think anything about my development set up is very unconventional.

Are these features supported properly if you build from source? Or are they not supported at all?
