On Windows 10 I have installed:

P:\W10>python --version
Python 3.10.0

P:\W10>pyinstaller --version
4.7

I can compile a VERY simple Python program:

P:\W10>type argv.pv
#!/usr/bin/python3

import sys

for a in sys.argv: print("["+a+"]")

P:\W10>pyinstaller.exe --onefile tcpbm.py

But I can run it only once:

P:\W10\dist>argv a b
[dist\argv]
[a]
[b]

P:\W10\dist>argv a b
The process cannot access the file because it is being used by another process.

P:\W10\dist>argv 1 2 zzz
The process cannot access the file because it is being used by another process.

Compiling a little more complex program (with net IO) fails:

interpret these error messages. What is going wrong?
