ASUS ROG Flow X13 GV301QE (Ryzen 9 5900HS) - Intel AX200 Bluetooth issue

[Varo]

Hardware:

• Laptop: ASUS ROG Flow X13 GV301QE
• CPU: AMD Ryzen 9 5900HS
• Wi-Fi/Bluetooth: Intel AX200 (USB VID:8087 PID:0029)
• macOS: Ventura 13.7.8
• OpenCore: 1.0.7
• SMBIOS: MacBookPro16,3

Current status:

• Wi-Fi works correctly.
• Battery and audio are fixed and working.
• Bluetooth USB controller is detected:
  • Vendor ID: 0x8087 (Intel)
  • Product ID: 0x0029
  • Built-In: Yes
•  
• Bluetooth can be turned ON in System Settings.
• Mac becomes discoverable (“This Mac is discoverable as …”).

Problem:

• Nearby Devices always remains empty.
• No devices are discovered (mouse, headphones, phone).
• Bluetooth behaves like a “phantom” device: it is ON but performs no scanning or pairing.

Diagnostics:

• system_profiler SPUSBDataType shows Intel Bluetooth controller correctly.
• ioreg shows IntelBluetoothFirmware and IntelBTPatcher loaded.
• Bluetooth logs contain NoBLEScan.
• Previously I also saw:
  • Address: NULL
  • State: OFF
  • Bluetooth Power State: deadbeef
  • Chipset: BCM_4350C2

Things already tried:

• Reset NVRAM
• Different versions of IntelBluetoothFirmware
• Different combinations of:
  • IntelBluetoothFirmware.kext
  • IntelBTPatcher.kext
  • BlueToolFixup.kext
  • IntelBluetoothInjector.kext
• Rebuilt USB mapping and verified Bluetooth USB port
• Updated OpenCore and kexts
• Lilu stable version (1.7.2). 

Has anyone managed to get Intel AX200 Bluetooth fully working on an ASUS ROG Flow X13 GV301QE (Ryzen 9 5900HS) running Ventura?

Update bluetooth kexts. These kexts work good.
