Errors with building and distributing

Hi all,
I’m experimenting with building and distributing and so far, I have a strange problem. I hope those experienced with this can offer help. To start, I wrote a very simple application that changes the colour of a button whenever it is pressed, here is the code:

from direct.showbase.ShowBase import ShowBase
from direct.gui.DirectGui import *
import random

class run_me(ShowBase):
    def __init__(self):
        ShowBase.__init__(self)
        #Actor tests here:
        #self.pandaActos = Actor()
        base.setBackgroundColor(0.5,0.8,0.7,1)
        currentId=0
        #put a button at the centre:
        self.newPackage=DirectButton(text = ("New Package", "New Package", "New Package", "New Package"),pos=(-0.0312056, 0, 0.156028),scale=.05)
        self.newPackage["command"]=self.changeColor
        
    def changeColor(self):
        coloList=[]
        for i in range(4):
            colG=random.uniform(0,1)
            coloList.append(colG)
        self.newPackage["frameColor"]=(coloList[0],coloList[1],coloList[2],coloList[3])
            
w = run_me()
w.run()

And here is what my setup.py looks like:

from setuptools import setup

setup(
    name='colouring',
    options={
        'build_apps': {
            # Build asteroids.exe as a GUI application
            'gui_apps': {
                'colouring': 'testdist.py',
            },

            # Set up output logging, important for GUI apps!
            'log_filename': '$USER_APPDATA/colouring/output.log',
            'log_append': False,

            # Include the OpenGL renderer and OpenAL audio plug-in
            'plugins': [
                'pandagl',
                'p3openal_audio',
            ],
            
            #target os-types to build for
            'platforms': ['manylinux2010_x86_64', 'macosx_10_9_x86_64', 'win_amd64'],
        }
    }
)

And here is what I added to the requirements.txt file:

panda3d~=1.10.14

When building, I ran into a few errors, upon trying to run the executable, the output.log file yields this error:

When actually running the ppython setup.py bdist_apps command, this is the output:

As can be seen, there are some errors it raises, but what could be causing them for such a rudimentary application?
I greatly appreciate any help offered,

Thanks in advance.

EDITS:

I added the entire output.log file. Upon running the executable, absolutely nothing happens, but the output.log file is modified as pasted here. What could be causing this? I’m at an impasse…

So, upon uninstalling and re-installing Panda3d, the issue seems to have been resolved, albeit with certain warnings still persisting:

There are some missing modules: ['importlib.metadata']
...
There are some missing modules: ['_posixsubprocess']

I will assume these are negligible for now.
