Endless trace messages when converting python kivy program to exe file with pyinstaller

So i am trying to convert an example kivy program into an exe standalone file from this documentation page, just as a bleak example to investigate why my pyinstaller and kivy do not work:
https://kivy.org/doc/stable/tutorials/firstwidget.html

A .kv file is not needed for this particular implementation.

The code is in the file main2.py:

from random import random
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.button import Button
from kivy.graphics import Color, Ellipse, Line


class MyPaintWidget(Widget):

    def on_touch_down(self, touch):
        color = (random(), 1, 1)
        with self.canvas:
            Color(*color, mode='hsv')
            d = 30.
            Ellipse(pos=(touch.x - d / 2, touch.y - d / 2), size=(d, d))
            touch.ud['line'] = Line(points=(touch.x, touch.y))

    def on_touch_move(self, touch):
        touch.ud['line'].points += [touch.x, touch.y]


class MyPaintApp(App):

    def build(self):
        parent = Widget()
        self.painter = MyPaintWidget()
        clearbtn = Button(text='Clear')
        clearbtn.bind(on_release=self.clear_canvas)
        parent.add_widget(self.painter)
        parent.add_widget(clearbtn)
        return parent

    def clear_canvas(self, obj):
        self.painter.canvas.clear()


if __name__ == '__main__':
    MyPaintApp().run()

i used the command: (tried with and without the "--onefile")

pyinstaller --onefile -w main2.py

Everything goes good until pyinstaller outputs this endless list of trace messages that don't stop and keep on printing in the terminal:

The process generates this main2.spec file though:

# -*- mode: python ; coding: utf-8 -*-


block_cipher = None


a = Analysis(
    ['main2.py'],
    pathex=[],
    binaries=[],
    datas=[],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='main2',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    console=False,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)
coll = COLLECT(
    exe,
    a.binaries,
    a.zipfiles,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='main2',
)

and when i run the "exe file" that has been created, it gives me this recursion error as an error message (without opening any application window):

Failed to execute script 'main2' due to unhandled exception: maximum recursion depth exceeded while calling a Python object

Traceback (most recent call last):
  File "logging\__init__.py", line 1084, in emit
AttributeError: 'NoneType' object has no attribute 'write'

During handling of the above exception, another exception occurred:

... <same exception repeated many times> ...

I also tried to follow the .spec file changes given here:
https://www.youtube.com/watch?v=NEko7jWYKiE

...without any luck, it gives me the same traces and error message.

Additional information:
PyInstaller: version 5.11.0
Python: version 3.8.3

Any answers to how i can convert it to an exe file and get rid of these errors will be appreciated.

I also had the same problem. Downgrading the pyinstaller version fixed it. My advice would be to change your pyinstaller version to 5.6.2. First run

pyinstaller --onefile main2.py

Then edit the created spec file like this.

# -*- mode: python ; coding: utf-8 -*-

from kivy_deps import sdl2, glew
from kivymd import hooks_path as kivymd_hooks_path

block_cipher = None
app_name = 'Your App Name'
win_icon = '.\icon.ico'


a = Analysis(
    ['main.py'],
    pathex=[],
    binaries=[],
    hiddenimports=[],
    datas =[('./main.kv', '.'), ('./*.ico', '.')],
    hookspath=[kivymd_hooks_path],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    a.binaries,
    a.zipfiles,
    a.datas,
    *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
    name=app_name,
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    upx_exclude=[],
    runtime_tmpdir=None,
    console=False,
    icon=win_icon,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)

It's not necessary to edit it this way, but I'm adding it here anyway. Finally run

pyinstaller main.spec

It will be extracted as YourApplicationName.exe to the folder named dist.
