I dont't know why ImmSetOpenStatus() not work in the lastest IME on Windows 11?

Question

 I use ImmSetOpenStatus() to open/close Input Method Editor (IME). ImmSetOpenStatus()  work correctly in previous version of IME in Windows 10. However, ImmSetOpenStatus() does not work in the lastest IME on Windows 11. May you tell the reason?
 

This is my code:

    if (status == FALSE) // Close IME

    {

        //turn off IME and conversion mode

        dwConversion = IME_CMODE_FULLSHAPE | IME_CMODE_ALPHANUMERIC;

        ImmSetConversionStatus(hIMC, dwConversion, 0);

        ImmSetOpenStatus(hIMC, FALSE);

    }

    else // Open IME

    {

        //set conversion mode

        switch (GetCurrentLanguageCode())

        {

        case JP:

            dwConversion = IME_CMODE_JAPANESE;

            ImmSetConversionStatus(hIMC, dwConversion, 0);

            ImmSetOpenStatus(hIMC, TRUE);

            break;

        case CN:

            dwConversion = IME_CMODE_CHINESE;

            ImmSetConversionStatus(hIMC, dwConversion, 0);

            ImmSetOpenStatus(hIMC, TRUE);

            break;

        case KR:

            dwConversion = IME_CMODE_ROMAN | IME_CMODE_FULLSHAPE | IME_CMODE_HANGUL;

            ImmSetConversionStatus(hIMC, dwConversion, 0);

            ImmSetOpenStatus(hIMC, TRUE);

            break;

        default:

            break;

        }

    }
