Pycharm Debugger not working in Python Console for Docker-Compose interpreter

Working on an application, my test suite debugger takes a solid six minutes to boot up and run the code I care about. Annoying, but a separate problem from this post.

The class I wanted to test is simple enough, so I tried launching the Python Console. The console launches fine, the remote docker interpreter does what is expected. Code runs, all is well.

However, when I try to run the debugger in the console, I get the following output.

python /opt/.pycharm_helpers/pydev/pydevconsole.py --mode=client --host=host.docker.internal --port=51801

Failed to connect to target debugger.

The one thing I note is that the port the debugger attempts to connect to is a mismatch from the `--port` argument, but I'm not sure if that's germane.

Relevant information:

• macOS 12.6.5 (MacBook Pro, 2019, Intel Core i7)
• PyCharm 2023.1
• Remote Docker interpreter

Possibly relevant information:

• This worked in a previous version of PyCharm; I updated to 2023.1 in order to see if it would help the test suite launch faster. Spoiler: it did not.
• Something changed in a recent version of Docker? PyCharm? that moved `/var/run/docker.sock` to `$HOME/.docker/run/docker.sock`, so I have to run `sudo ln -s $HOME/.docker/run/docker.sock /var/run/docker.sock` to make the PyCharm remote interpreter work
