Pyinstaller Not compiling exe | --onefile

[tarik setia]

I am trying to package kivy and CEFpython into single exe.

Pyinstaller is not compiling EXE on my windows machine. It gets stuck at "111686 INFO: Building PKG (CArchive) PKG-00.pkg" and then throws errors.

Build logs : https://gist.github.com/tariksetia/e2fe3b2d0e013303c37b6a4054173dc6

Spec file : 

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

from kivy_deps import sdl2, glew, angle

import os, platform

if platform.system().lower() == 'windows':

    os.environ['KIVY_GL_BACKEND'] = "angle_sdl2"

block_cipher = None

assets_files = [

    ('ipaws/assets','assets'),

    ('ipaws/widgets/kvs/*.kv', '.'),

    ('ipaws/screens/kvs/*.kv', '.')

]

a = Analysis(['ipaws\\app.py'],

             pathex=['C:\\Users\\IEUser\\Desktop\\warn'],

             binaries=[],

             datas=assets_files,

             hiddenimports=['sqlalchemy.ext.baked', 'plyer.platforms.win.filechooser'],

             hookspath=['.'],

             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 + angle.dep_bins)],

          [],

          name='ipaws',

          debug=False,

          bootloader_ignore_signals=False,

          strip=False,

          upx=True,

          upx_exclude=[],

          console=True,

          runtime_tmpdir=None

          )

the command I am using is 

python -m PyInstaller --clean --onefile ipaws.spec

Any help is hugely appreciated

Thanks!
