[Python] Run the file.exe before exiting the Python program? [closed]

You need to run the exe file and exit the Python program, which is packaged in an executable file. I've tried different ways, but a message appears after each option.enter image description here

As far as I understand, calling another program does not allow you to close the main application.

I've tried these methods, but the message still appears.

from subprocess import Popen, CREATE_NO_WINDOW, DETACHED_PROCESS,
CREATE_NEW_PROCESS_GROUP

'''
Replace
os.system(f'"{os.path.join(DOWNLOAD_TEMP_PATH, new_exe_name)}"')
With the Followings:
'''
Popen(\[new_exe_name\], shell=True,
creationflags=CREATE_NO_WINDOW | DETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP)

# \---------------------------------------------------------------------

import os
os.spawnlp(os.P_NOWAIT, 'cp', 'cp', '/path/large-file.db', '/path/dest')

# \----------------------------------------------------------------

from subprocess import Popen
DETACHED_PROCESS = 0x00000008
cmd = \[
sys.executable,
'c:\\somepath\\someprogram.exe',
parm1,
parm2,
parm3\]
p = Popen(
cmd, shell=False, stdin=None, stdout=None, stderr=None,
close_fds=True, creationflags=DETACHED_PROCESS,
)
