ModuleNotfounderror webdriver_manager.core

[rscl....@gmail.com]

OS: Windows 11

Python Version: 3.7.7

IDE: Pycharm

Pyinstaller Version: 3.6

Command to generate executable:
pyinstaller --onefile --icon=slicon.ico SecureLogin_V2.1.py

The executable gets generated fine. No errors reported

But when I run the executable file, I get the error as per the below screenshot:

pip install webdriver-manager

pip install webdriver_manager

Both the above commands return "Requirement already satisfied"

Can someone please help me how to fix this?

TIA
