Python code works on cmd and VScode but not on powershell or pyinstaller

I have written a python script to save a book. It takes screenshots, turns pages(pyautogui click) and combines the screenshots into a PDF.

This is what happens on executing code in vscode:

PS C:UsersAdmin> & C:/Users/Admin/AppData/Local/Programs/Python/Python39/python.exe "c:/Users/Admin/Desktop/New folder/Windows_v1.py"
On page 1
On page 2
On page 3
On page 4
Combining PDF
PS C:UsersAdmin> 

This is what happens in cmd

C:UsersAdminDesktopNew folder>python Windows_v1.py
On page 1
On page 2
On page 3
Combining PDF
C:UsersAdminDesktopNew folder>

This is what happens on powershell

PS C:UsersAdminDesktopNew Folder> python Windows_v1.py
On page 1
On page 2

…and it just stays there(tested for 15 minutes).

The script:

# Not in standard library- img2pdf, pyautogui, PIL
import img2pdf

from PIL import ImageGrab

#Main window creation

# Top level window

I have tried:

1. Rebooting
2. Re-installing all the required pip modules

Answer

Turn out the auto-clicker was the problem with PowerShell. Whenever it used to click on the PowerShell command line, it paused. Fixed using this answer: https://serverfault.com/a/205898
