Issue connecting python to Autocad

Question

I'm currently working with AutoCAD in Python and recently attempted to establish a connection between Python and AutoCAD. I wrote a simple script to test the connection:

from pyautocad import Autocad

def main():
    # Create an instance of AutoCAD
    acad = Autocad()

    # Check if there's an active document
    print(acad.doc.Name)

if __name__ == "__main__":
    main()

However, I encountered the following error message:

Traceback (most recent call last):
  File "C:\Users\engli\PycharmProjects\pythonProject\Architecture\create a line.py", line 12, in <module>
    main()
  File "C:\Users\engli\PycharmProjects\pythonProject\Architecture\create a line.py", line 8, in main
    print(acad.doc.Name)
          ^^^^^^^^

OSError: [WinError -2147221005] Invalid class string

The error message Invalid class string suggests that the COM object for AutoCAD cannot be found or accessed. I'm unsure how to resolve this issue. Any help would be greatly appreciated.
