Why does mozilla firefox compile error?

Question

Mozilla Firefox

Hello. To begin with, I will say that I need to compile this assembly of firefox
https://github.com/vektort13/AntidetectFirefox
By installing all the necessary software and using the installation instructions
https://developer.mozilla.org/en-US/docs/Mozilla/D. ..
I was able to compile pure firefox into a binary and run the browser on a Windows 10 x64 machine.
This indicates that I installed the software correctly.
Now I'm trying to compile the source
https://github.com/vektort13/AntidetectFirefox
and I get

[email protected] /c/mozilla-source/vector
$ ./mach bootstrap
mach bootstrap is not fully implemented in MozillaBuild

Please choose the version of Firefox you want to build:
1. Firefox for Desktop Artifact Mode
2. Firefox for Desktop
3. Firefox for Android Artifact Mode
4. Firefox for Android

Note on Artifact Mode:

Firefox for Desktop and Android supports a fast build mode called
artifact mode. Artifact mode downloads pre-built C++ components rather
than building them locally, trading bandwidth for time.

Artifact builds will be useful to many developers who are not working
with compiled code. If you want to work on look-and-feel of Firefox,
you want "Firefox for Desktop Artifact Mode".

Similarly, if you want to work on the look-and-feel of Firefox for Android,
you want "Firefox for Android Artifact Mode".

To work on the Gecko technology platform, you would need to opt to full,
non-artifact mode. Gecko is Mozilla's web rendering engine, similar to Edge,
Blink, and WebKit. Gecko is implemented in C++ and JavaScript. If you
want to work on web rendering, you want "Firefox for Desktop", or
"Firefox for Android".

If you don't know what you want, start with just Artifact Mode of the desired
platform. Your builds will be much shorter than if you build Gecko as well.
But don't worry! You can always switch configurations later.

You can learn more about Artifact mode builds at
https://developer.mozilla.org/en-US/docs/Artifact_builds.

error: missing key: 'url'
Error running mach:

    ['bootstrap']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

CalledProcessError: Command '['c:\\users\\user\\appdata\\local\\temp/rustup-init.exe', '--no-modify-path', '--default-host', 'x86_64-pc-windows-msvc', '--default-toolchain', 'stable', '-y']' returned non-zero exit status 1

I would be very grateful for help in solving. But if you don’t have a solution, explain to me this line and what this component is responsible for

info: syncing channel updates for 'stable-x86_64-pc-windows-msvc'
error: missing key: 'url'
Error running mach:

I think there is a bug in this component.
