Problem Description

Unable to successfully install or develop plugin for 6.0.3 Spyder for Windows (through Miniforge). I am trying to develop a simple plugin for Spyder before branching out into more complex functionalities, but I am unable to even get a simple "Hello World" plugin to appear in the View -> Panes or even the Dependencies drop down. It appears as an entrypoint for spyder plugins, lists as installed through miniforge, and even can be imported in the Ipython console, yet it does not appear in the application interface itself.

What steps reproduce the problem?

1. Install Miniforgex86_64
2. Install Spyder through wiki Conda steps (with Mamba) https://docs.spyder-ide.org/current/installation.html
3. Setup directory (see attachment) as follows within C:\Users%USERNAME%\miniforge3\envs\spyder-env\Library\plugins

spyder-helloworld/
├── setup.py
├── helloworld_plugin/
├── init.py
└── plugin.py
5. With active spyder environment in miniforge prompt navigate to spyder_helloworld folder
6. Install using pip install -e .
7. start Spyder in environment with spyder

What is the expected output? What do you see instead?

Expected output is to have a pane available under view -> panes menu tab. It is not present.
Expected to have it populated under Spyder plugins under Help -> Dependencies. Not present either.
Using spyder --debug does not do anything. Expected it to start Spyder with debugging.
It is listed under pip list in the IPython Console

Python 3.12.8 | packaged by conda-forge | (main, Dec 5 2024, 14:06:27) [MSC v.1942 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.
