How to run example.py from a script?

Question

Python

Hello! I wrote a bot in tg and I'm trying to run a script from this bot with another bot, it starts through os.startfile (), but the second bot does not respond to / start, but if you run a simple script, like print () inside, then everything starts. What could be the problem? I tried subprocess.call, popen, run, nothing works ((already broke my whole head

upd
The script is launched via subprocess.call(['python', file]) but this second bot does not respond to commands, but if you run exactly the same bot with the only function hello, then the bot in tg answers 0_o

I need to run a large script on 2k lines, only with a different token
