Python app taking a long time to open using cx_freeze

Question

I am building an app with tkinter, cx_freeze and I have Anaconda installed. The app is taking a really long time to open (30 seconds). I think it has something to do with the tzdata that is in the ananconda tcl folders as I can see it opening these up when I ran a process monitor on it. If I delete these from my anaconda folders, will this break anything? Is there a way around this?

from cx_Freeze import setup, Executable
import os.path
base = None    
PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))
os.environ['TCL_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tcl8.6')
os.environ['TK_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tk8.6')


executables = [Executable("RunExcelMacro.py", base=base)]

packages = ["idna","tkinter","os","win32com.client"]
options = {
    'build_exe': {    
        'packages':packages,'include_files':[
            os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tk86t.dll'),
            os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tcl86t.dll'),
         ],
    },    
}


#os.environ['TCL_LIBRARY'] = r'C:\ProgramData\Anaconda3\tcl\tcl8.6'
#os.environ['TK_LIBRARY'] = r'C:\ProgramData\Anaconda3\tcl\tk8.6'
setup(
    name = "Background Excel Executor",
    options = options,
    version = "1.0",
    description = 'Runs an excel macro in the background',
    executables = executables
)
