[CORE] Fixed base class parameter property access

On Windows with MSVC compiler the following error was raised error C2036: 'void *':
unknown size. The issue stems from how void* is being handled in your Cython code,
particularly the way parameters is accessed. On Windows, the MSVC compiler enforces
stricter type-checking and does not allow dereferencing a void* directly, which
causes errors like unknown size or invalid access.
