What configurations should I set to support avx512 instructions like _mm512_setr_epi32 in Debug mode?

I wrote a cpp file including avx512 instructions with VS2019, the complication is complete with no error, but when I tried to debug, an error of "Illegal Instruction" came out near the _mm512_setr_epi32, as well as the other instructions. So I want to know what can I do to support this problem to debug with avx512 instructions. Thank you very much!

    Hi smithtony-7804.

    I'm sorry that I misunderstanding something in previous replies. I did some tests about "__m512" in vs2019 16.8, and found that it just can be compiled in VS 2019 which like this blog says.

    Sorry for my mistakes, I have corrected my previous replies.

    Best Regards,
    Dylan

    Thank you for your answer, but this is no what i want. I will explain it with an example below.
    This is my code for example:
    //start//
    1:#include "immintrin.h"
    2:int main()
    3:{
    4: __m512i x = _mm512_setr_epi32(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15);
    5: return 0;
    6:}
    //end//
    A breakpoint is set on the 4th line, when I try to run this code, the program crashed with an error of "Illegal Instruction". So my question is should I add some libs or make some special configuration to avoid this error. Thank you very much and I am looking forward for you answer.
