Timeout waiting for debug server to connect in VSCode when debugging embedded Python

Question

I am trying to 'locally" debug Python 3.8.10 embedded in my 64-bit Windows GUI application on Windows 10 with VSCode.
I know this works for many people - I want to what possibly I am doing wrong with how I am embedding python that is preventing the debugging from VSCode working. My approach to embedding the python interpreter seems pretty vanilla.

--- Starting attach to pid: 12720 ---

--- Connecting to 64 bits target (current process is: 64) ---

Running executable to inject dll.

OpenProcess with pid: 12720

VirtualAllocEx in pid: 12720

WriteProcessMemory in pid: 12720

loadLibraryAddress: 12720

Waiting for LoadLibraryA to complete.

Ok, finished dll injection.

Hi @Andrew Cunningham,

Welcome to Microsoft Q&A!

You are using Visual Studio Code, which is different from Visual Studio. The tag “Visual Studio” is related to Visual Studio, for more questions about Visual Studio Code, you can post it to the Stack Overview tagged visual-studio-code forum or GitHub repository where you would get professional support for this product.

Thanks for your understanding.

Sincerely,

Anna
