What is the bug or the crash?

Steps to reproduce the issue

1. Do !pip install loopstructural[visualisation,export] in QGIS console

2. Install zipfile

3. Result:
   Couldn't load plugin 'loopstructural' due to an error when calling its classFactory() method

ModuleNotFoundError: No module named 'LoopStructural'

Hi @markjessell did you install the libraries into the system environment using --break-system-packages? I wasn't able to install the external dependencies without this flag on linux. The only way I can get them working is to start qgis using a conda environment with loopstructural installed. The plugin works for this approach...

[markjessell]

I did not use --break-system-packages. I made a conda env, and then conda installed qgis. !pip install works for me on linux from the qgis console
