macOS not shutting down properly

I have a problem with my Hackintosh. When I click shutdown, the screen turns off and the OS shuts down, USB devices turn off, but the power is never fully removed. The fans start spinning on max and the built-in keyboard backlight is still lit. The screen is off, even if I use verbose mode.

USB is mapped with USBToolBox. FixShutdown-USB-SSDT.aml ACPI patch is present and configured for all USB controllers (I have two, a normal and a Thunderbolt/USB-C mix one) using this guide. It was working on Monterey and stopped working on Ventura, and still broken on Sonoma.

OS version is macOS Sonoma 14.2.1
OpenCore version is 1.0.0

Any help is appreciated!
