I try to build Firefox on macOS Monterey (Intel), `./mach build` fails with this error:
```

 0:22.12 The error occurred in code that was called by the mach command. This is either

 0:22.12 misbehaving, you can also inspect the dependencies of bug 1543241.
 0:22.12 If filing a bug, please include the full output of mach, including this error
 0:22.12 message.

``` 

I try to recreate my environment with updating brew, deleting `~/mozbuild`, recreating it from `bootstrap.py` as [explained in the document](https://firefox-source-docs.mozilla.org/setup/macos_build.html), but anything fixes this issue.
