   • Recreating the engine is in general not a good idea and not recommended or supported
   • You need to manually unload any dlls loaded by your python script before recreating the engine

   For example PyScripter does something like this

     procedure UnloadPythonDLL(DLL: PWideChar);
     Var
       Module : HMODULE;
     begin
       MODULE := GetModuleHandle(DLL);
       if MODULE >= 32 then
         FreeLibrary(Module);
     end;
   
     if WasLoaded then
     begin
       UnloadPythonDLL('select.pyd');
       UnloadPythonDLL('_socket.pyd');
       UnloadPythonDLL('python3.dll');
       UnloadPythonDLL('_ssl.pyd');
       UnloadPythonDLL('win32file.pyd');
       UnloadPythonDLL('win32pipe.pyd');
       UnloadPythonDLL('win32event.pyd');
       UnloadPythonDLL('_win32sysloader.pyd');
       UnloadPythonDLL('unicodedata.pyd');
       UnloadPythonDLL('_ctypes.pyd');
       UnloadPythonDLL('_hashlib.pyd');
       UnloadPythonDLL('_asyncio.pyd');
       UnloadPythonDLL('_overlapped.pyd');
       UnloadPythonDLL('_bz2.pyd');
       UnloadPythonDLL('_lzma.pyd');
       UnloadPythonDLL('_queue.pyd');
       UnloadPythonDLL(PChar('pywintypes' + RegVersion + '.dll'));
     end;

   But you need to use the debugger to see what dlls your script loads.
