Description
I'm using kAFL-nyx to fuzz a Windows userland-target
On a Intel I7 7th generation it works fine but with the same setup/OS/harness on a Intel I7 12th generation I get decoding errors for some executions
The submitted range (.text section) by the harness is `7ffbdcf91000-7ffbddb9c9fc`

```
I tried it using nyx kernel 6.0 and 6.8 with the same result. I also tried using `mitigations=off ` , `noaltinstr` in GRUB and disabling e-cores in UEFI.
Do you have any tips on how to debug it?
