UserWarning: incompatible copy of pydevd already imported

[int19h]

When debugging this in a launch session:

# app.py
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "ok"

if __name__ == "__main__":
    app.run(debug=True)

The following output is produced:

> 'C:\Python\3.9-64\python.exe' 'c:\Users\pminaev\.vscode\extensions\ms-python.python-2022.20.0\pythonFiles\lib\python\debugpy\adapter/../..\debugpy\launcher' '61002' '--' '-m' 'flask' 'run' '--no-debugger' 
...
 * Restarting with stat

...

(it goes on to list all the files)

It doesn't seem to affect function, but the warning is obviously incorrect, since it's complaining about its own vendored copy.
