Access Violation issue facing for exe created using pyinstaller

I am trying to create a executable for one of the python script. When I try to run the application created using pyinstaller I am getting an error while trying to load the model using llama_cpp

> ValueError: Could not load Llama model from path: ...
Received error exception: access violation reading 0x0000000000000000

If I run the same application directly from pycharm its working fine but I face this issue only when I try to run the executable.
