Python plugin with venv not able to import module

Issue

I trying to create a Python plugin that uses a module not installed in pvpython already. I am using a venv to manage the dependencies and then setting the environment variable PV_VENV and using import paraview.web.venv as per this guide. The issue is that when I go to Tools > Manage Plugins... > Load New ... and select my plugin, I receive a ModuleNotFoundError. Before receiving the error, the line ParaView is using venv: <path-to-venv> is printed so I don't understand why the module cannot be found.

Information

I am using ParaView 5.12 in Ubuntu 22.04.4 LTS on Windows Subsystem for Linux.

Steps to Reproduce

1. Create a test directory: mkdir test and cd test

2. Create a virtual environment: python -m venv .venv

3. Activate the virtual environment and install dependencies:

$ source .venv/bin/activate
(.venv) $ pip install numpy intersect

4. Export PV_VENV environment variable: export PV_VENV="/home/<user>/test/.venv"

5. Create a test plugin for ParaView:

# plugin.py
import paraview.web.venv
import intersect

6. Open ParaView and load the plugin:

$ paraview &

then Tools > Manage Plugins... > Load New ... and select plugin.py

7. Observe the output in the terminal:

(.venv) $ ParaView is using venv: /home/<user>/test/.venv
( 168.986s) [paraview        ]vtkPVPythonAlgorithmPlu:173   WARN| Failed to load Python plugin:

  File "/home/<user>/test/plugin.py", line 3, in <module>
    import intersect
ModuleNotFoundError: No module named 'intersect'

Any ideas what is going on? I tried this a few weeks ago and I was able to load the plugin and import the module from the venv with no issues so I'm not sure what I'm doing differently/what has changed.

Thanks in advance :)
