Question: I'm trying to use the debugger in vs code (mac os big sur) with no success. I'm on the m1 macbook air. vs code insiders version. I've tried with all these python interpreters: 3.9.6 - /opt/homebrew/bin/python3 3.9.1 - /usr/local/bin/python3 3.8.2 - /usr/bin/python3 2.7.16 - /usr/bin/python I've tried with this launch.json file: { "version": "0.2.0", "configurations": [ { "name": "Python: Current File", "type": "python", "request": "launch", "program": "${file}", "console": "integratedTerminal" } ] }  This is the error that I always get:  /usr/bin/env /usr/local/bin/python3 /Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/launcher 50295 -- /Users/arch0n/Desktop/py-w3schools/2.py Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 197, in _run_module_as_main return _run_code(code, main_globals, None, File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 87, in _run_code exec(code, run_globals) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/__main__.py", line 45, in <module> cli.main() File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/cli.py", line 444, in main run() File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/cli.py", line 267, in run_file start_debugging(target) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/cli.py", line 257, in start_debugging debugpy.connect(options.address, access_token=options.adapter_access_token) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/common/compat.py", line 208, in kwonly_f return f(*args, **kwargs) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/__init__.py", line 135, in connect return api.connect(address, access_token=access_token) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/api.py", line 143, in debug log.reraise_exception("{0}() failed:", func.__name__, level="info") File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/api.py", line 141, in debug return func(address, settrace_kwargs, **kwargs) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/api.py", line 276, in connect _settrace(host=host, port=port, client_access_token=access_token, **settrace_kwargs) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/../debugpy/server/api.py", line 47, in _settrace return pydevd.settrace(*args, **kwargs) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/_vendored/pydevd/pydevd.py", line 2696, in settrace _locked_settrace( File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/_vendored/pydevd/pydevd.py", line 2819, in _locked_settrace py_db.enable_tracing(py_db.trace_dispatch, apply_to_all_threads=True) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/_vendored/pydevd/pydevd.py", line 1039, in enable_tracing pydevd_tracing.SetTrace(thread_trace_func) File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/_vendored/pydevd/pydevd_tracing.py", line 83, in SetTrace if set_trace_to_threads(tracing_func, thread_idents=[thread.get_ident()], create_dummy_thread=False) == 0: File "/Users/arch0n/.vscode-insiders/extensions/ms-python.python-2021.7.1053846006/pythonFiles/lib/python/debugpy/_vendored/pydevd/pydevd_tracing.py", line 349, in set_trace_to_threads result = lib.AttachDebuggerTracing( File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ctypes/__init__.py", line 387, in __getattr__ func = self.__getitem__(name) File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ctypes/__init__.py", line 392, in __getitem__ func = self._FuncPtr((name_or_ordinal, self)) AttributeError: dlsym(RTLD_DEFAULT, AttachDebuggerTracing): symbol not found  arch0n is my user directory.

Answer: I fixed the same issue I was having by rolling back to the prior version of ms-python.python extension. The problem seems to be in the extension and has yet to be resolved.
