使用 VS Code 调试 python 文件。断点抛出异常，断点被忽略

Question

尝试了多个不同的 python 文件。每次我尝试在 vs 代码中使用调试器并设置断点时，都会忽略断点并引发异常并且脚本继续运行。我一直在谷歌搜索和修补超过 2 小时，似乎无法弄清楚这里发生了什么。尝试重新启动PC，以管理员身份运行vs code，卸载/重新安装vs code的python扩展。试图挖掘回溯中提到的文件并查明似乎引发异常的函数，但我无法弄清楚它是从哪里调用的，或者它为什么引发异常。我对 Python 还是很陌生。在我的笔记本电脑上调试工作正常，但无论出于何种原因，我的桌面出现了这个问题。

Traceback (most recent call last):

    return cache[filename]

During handling of the above exception, another exception occurred:

    dir_contents = cache[resolved_lower] = os.listdir(resolved)
PermissionError: [WinError 5] Access is denied: 'C:\\Users\\Joel\\Local Settings' 

所以每次遇到断点时我都会得到这个回溯。看一下“pydevd_file_utils.py”中的“_original_file_to_client”函数，我们得到：

def _original_file_to_client(filename, cache={}):
    try:
        return cache[filename]
    except KeyError:
        translated = _path_to_expected_str(get_path_with_real_case(_AbsFile(filename)))
        cache[filename] = (translated, False)
    return cache[filename]

我无法弄清楚这个函数是从哪里调用的，或者预期的输出应该是什么。对此的任何帮助将不胜感激！

This 是一个类似的问题。文件名中的空格会导致此问题： “本地设置”、“应用程序数据”
