Imac Retina 5K, 27-inch, Late 2015: Black Screen

Installed OpenCore Legacy Patcher version 2.2.0 and upgraded from Monterey to Sequoia 15.2.
After the Sequoia install I ran the post-install root patches.
The first thing noticeable was that the OS took some time to log in and was a bit sluggish in general. Changing the wallpaper from an active/motion to a solid color fixed those issues.

The issue now is that randomly, when the system is asleep it will get hung up. In more detail, the screen will be blank and no movement of the mouse or press of the keyboard will wake the system. When this occurs, the system must be forced off by holding the power button and then press again to power the system back on. When this is done, the system gives the Mac notice during bootup that something went wrong and says to wait or press a key to continue the boot.

Here are the power settings currently on the system.

• Put hard disks to sleep when possible: Enabled
• Enable Power Nap: Disabled
• Screen Saver: Disabled

The system has a 500 GB SSD installed

I'm not certain about the different partitions that OPL created. When booting it prompts to boot to the disk or to install Sequoia. I'm not sure why it would prompt to install Sequoia each time as it's already installed.

Let me know if you would like further info such as the system report and I can share it via Google Drive.
