Arch Linux

Description:

xonsh not working properly when started in gnome environment on endeavouros

Additional info:
* package version(s) - 0.13.4
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:

on a fresh install of endeavouros with gnome desktop preselected when starting xonsh one will get this python related warning:

```
/usr/lib/python3.10/site-packages/prompt_toolkit/eventloop/utils.py:118: DeprecationWarning: There is no current event loop
return asyncio.get_event_loop_policy().get_event_loop()
```

this will result in not properly evaluating the prompt, e.g. gitstatus won't show up. I am just scrating the surface here, but would like to get the ball rolling.

I tried both, installing the KDE desktop and just installing xonsh and python-prompt-toolkit in the live environment. Both work without the Warning and gitstatus is just fine.

I know this is most likely not a xonsh bug but that is where it hurts for me.
