I tried the following code，I am trying to add a custom MetaPathFinder to listen for module loading

import importlib.util
import sys
from importlib.abc import MetaPathFinder


class ModuleLoadListener(MetaPathFinder):
    def find_spec(self, fullname, path, target=None):
        for finder in sys.meta_path:
            if finder == self:
                continue
            spec = finder.find_spec(fullname, path, target)
            if spec is not None:
                spec.loader = CustomLoader(spec.loader)
                return spec

        return None


class CustomLoader(importlib.abc.Loader):
    def __init__(self, loader):
        self.loader = loader

    def create_module(self, spec):
        return self.loader.create_module(spec)

    def exec_module(self, module):
        return self.loader.exec_module(module)


sys.meta_path.insert(0, ModuleLoadListener())

import requests

But he had an abnormality，But there are some modules that do not report errors when imported

  File "D:appdeveloperpy3python3.11Libsite-packagesrequests-2.31.0-py3.11.eggrequestsutils.py", line 63, in <module>
    DEFAULT_CA_BUNDLE_PATH = certs.where()
                             ^^^^^^^^^^^^^

    raise FileNotFoundError("Can't open orphan path")
FileNotFoundError: Can't open orphan path

Am I doing this right？
