Please disable Hyper-V then try again. Or try the new version of HAXM v7.8.0.

I install the latest HAXM v7.8.0, and my CPU is 12900KS, but when I run

C:\Users\sooro>"C:\Program Files\Intel\HAXM\checktool.exe"
CPU vendor          *  GenuineIntel
Intel64 supported   *  Yes
VMX supported       -  No

Thanks for your feedback. You may follow the wiki page to configure your Windows host and then install HAXM v7.7.1.

@wcwang exactly, I try to configure my system based on your wiki page, but my problem does not resolved. I think new Windows Kernel does not work correctly with HAXM, as you can see in Hardware acceleration for emulator performance (Hyper-V & HAXM)

On Windows 10 October 2018 Update (RS5) and higher, you only need to enable Hyper-V, as it will use Windows Hypervisor Platform (WHPX) automatically.

The other note is, why VMX and EPT says NO ?

[wcwang]

Thanks for your reply. If Hyper-V is on, the CPUID instruction cannot read real value of VMX and EPT. Have you ever checked the Sandbox status described in wiki page?
