[Python] GIMP_wire_read error upon adding python script in correct folder

I am trying to learn GIMP 2.10.38 with python and I don't know either that well, so I tried adding a simple python script but it doesn't show up in GIMP at all. Here is the script I added:

#!/usr/bin/env python
from gimpfu import *

def simple_plugin(image, drawable):
gimp.message("Hello from a simple plugin!")

register(
"python-fu-simple-plugin",
"Simple Plugin Test",
"A simple test plugin",
"Your Name",
"Your Name",
"2024",
"<Image>/Filters/Simple Test", # Or any menu location
"RGB*",
[],
simple_plugin,
)

main()


The script is in the correct folder - confirmed that in preferences - folders - plug-ins Searching online I came across the --verbose argument and that led me to this error:

Querying plug-in: 'C:\Users\Prafulla\AppData\Roaming\GIMP\2.10\plug-ins\simplepy.py'
gimp-2.10: LibGimpBase-WARNING: gimp-2.10: gimp_wire_read(): error


I know it is a general error related to communication within GIMP but couldn't find enough information online. I have tried a reinstall already, but not tried deleting all folders manually yet. Any idea how I should proceed?
