mac M2 cannot open devcontainer with runArgs arch=amd64

Shortly speaking I need a devcontainer running `linux/amd64` type of image. Below is my `devcontainer.json`:
```json
// For format details, see https://aka.ms/devcontainer.json. For config options, see the
// README at: https://github.com/devcontainers/templates/tree/main/src/python
{
"name": "Python 3",
"build": {
"dockerfile": "Dockerfile",
"context": "."
},

"runArgs": [
"--userns=keep-id",
"--arch=amd64",
],
"containerEnv": {
"HOME": "/home/core"
},
"remoteUser": "core",
"workspaceMount": "source=${localWorkspaceFolder}/,destination=/home/core/,type=bind,consistency=cached",
"workspaceFolder": "/home/core/",
}
```
The Dockerfile:
```
FROM --platform=linux/amd64 python:3.10.13-slim-bullseye
```

I am running **Podman** on a **Mac M2 13.5**:

❗️Without `arch=amd64` in `runArgs` section everything works fine. With it, though, it seems that something bad is happening with the port forwarding. I am attaching some parts of devcontainer logs (trimmed for visibility). I **turned on ** trace logging for that:
