Windows 10 Qemu Intel haxm "-accel hax: invalid accelerator hax"

I'm trying to get Intel Haxm acceleration working on qemu/windows 10.

I followed this guide..

https://www.qemu.org/2017/11/22/haxm-usage-windows/

I have Virtualization enabled in bios, hyper-v disabled, and haxm 7.8.0 installed. I have qemu 9.0.0 installed form binary installer from..

https://qemu.weilnetz.de/w64/

when i try to launch a VM with option -accel hax i get this message:

C:\Program Files\qemu\qemu-system-x86_64.exe: -accel hax: invalid accelerator hax

This is the complete powershell script i'm using to launch the VM.
