[Python] How to properly configure IPOPT solver in Python virtual environment with CasADi?

I'm working on a Python project using CasADi with IPOPT solver, but encountering a shared library loading error. Here's my setup:

my_project/
│
├── venv/
│ ├── Includes
│ ├── Lib
│ └── Scripts
│
├── src/
│ ├── codes.py
│ └── ...
│
├── main.py
│
└── ...


Casadi has been installed in Lib/site-packages, and libcasadi_nlpsol_ipopt.dll and libcasadi_nlpsol_ipopt.dll.a is also included.

However, when running this basic IPOPT example in main.py:

opti = ca.Opti()
x = opti.variable()
opti.minimize(x**2)
opti.solver("ipopt", opts)
sol = opti.solve()


I get the following error: "WARNING(".../casadi/core/casadi_os.cpp:166: Assertion "handle!=nullptr" failed: PluginInterface::load_plugin: Cannot load shared library 'libcasadi_nlpsol_ipopt.dll'"

How can I properly configure IPOPT in my virtual environment to resolve this shared library loading issue?
