trace3D broken under Windows (not a #353 regression)

Brief description

Using the following sample code results in a traceback on Windows 11 using Python 3.11:
a,u=traceroute(["www.python.org", "google.com","slashdot.org"])
a.trace3D()

Scapy version

2.5.0.dev40

Python version

3.11

Operating system

Windows 11 Pro

Additional environment information

No response

How to reproduce

import scapy
from scapy.all import *
a,u=traceroute(["www.python.org", "google.com","slashdot.org"])
a.trace3D()

Actual result

traceback is:

raise RuntimeError('''
RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

Start at scapy/layers/inet.py around trace3D, where the traceback shows multiprocessing.Process.start() is called. Reproduce the sample on Windows 11 with Python 3.11 and inspect the spawn-related failure; done means trace3D runs without the reported traceback.
