Sonoma 14.5 black screen after awake

Hello alltogether,

I've recently built an EFI based on the OpenCore guide and GitHub https://github.com/mikigal/ryzen-hackintosh for Sonoma 14.5. Everything runs smoothly except for two issues:

1. After sleep, the system fails to wake up. The monitor lights up but then shows "no signal" and repeats this process. ( I suspect that the system has woken up, but the monitor remains black. This is because I noticed that the random keystrokes I made during the wake-up process appeared in my open note file after restart )
2. The system automatically restarts after shutting down.

I have followed the sleep troubleshooting guide on OpenCore but have not made any progress. Additionally, I tried using HibernationFixup.kext without any success.

Now, I suspect the issue might be related to the GPU, as it is biggest difference between the me and the existing (same motherboard, 7700 vs 7800x3d, and RX580 vs 7900 XTX)

My hardware is as follows:

• CPU: Ryzen R7 7700
• Motherboard: Asrock B650M PG Riptide
• GPU: XFX RX 580 2304sp (with Sapphire VBIOS, using HDMI connect to a 4K display)
• RAM: 32 GB (2x16GB) Adata DDR5 6000Mhz CL32
• Wifi/BT: None
• Opencore version: 1.0.0

By the way, is there any way to log in this situation? Debugging is too difficult without logs.

Any advises would be helpful thanks.
