Additional context

Installed from source using micromamba for env creation and installed via python dev_install.py -e --cli.

Hi, thanks for this. We can't directly support this OS, specifically, but did you also install the Linux-specific components?

https://docs.openbb.co/cli/installation#linux-requirements

Additionally, CLI is not really suitable for VMs or Docker.

[fleimgruber]

Thanks for checking back.

I would look into it myself, but I don't get any promising lead from the traceback - I would not even know where to begin, probably starting from the pywry dependency? Regarding Linux-specific components: Yes, Rust and Webkitgtk are both installed system-wide.

CLI is not really suitable for VMs or Docker.

Thanks for mentioning. Just to be clear, I am not running this in a VM or Docker.

It's going to be something related to PyWry - window creation - or environment contamination via $PATH priorities of Python libraries and executables
