Kernel panic issue

Hi guys,
Today I got this issue:

What does it mean and what can I do to fix it?
My rig has this component:

  • Asus Tuf B550 plus Wi-Fi
  • Ryzen 3900X
  • 2 x Corsair vengeance 16 GB
  • RX 6600
  • RX 6600 XT

I have already try to use just a ram in different slot and I also try to use just one gpu, I try also tu run recovery mode to do a check and also run memtest but no way to fix it.

This issue happened after a full week of work, after I updated mobo bios and after I try a quick undervolt of cpu (bringing it at 1.0 V)

Thank you for your support

Edit: Currently I use a usb drive to launch HiveOS, but I also try to use an hard disk with the same result.
