How do you switch graphics?
Did you try to change the tty when you boot into a black screen?

Also, Go to /usr/share/vulkan/icd.d/ and check if your GPU’s .json file is present. Make sure it does not have any other extension like .bak(i.e. nvidia_icd.json.bak)

I switch it from bios menu. I just switched tty to login through X11 and test after getting the black screen on wayland. Here’s the file i have on the system.

nvidia_icd.json
{
    "file_format_version" : "1.0.0",
    "ICD": {
        "library_path": "libGLX_nvidia.so.0",
        "api_version" : "1.3.278"
    }
}

The mux switch? I have no experience with the mux switch.
I am gonna guess that it completely disables the iGPU when you change it in bios?

Yes it completely shuts off the iGPU when i change it in the bios.

here’s the bios menu

One last thing that you can try is install Optimus-manager-qt and in it, change the startup mode to Nvidia. I think you might need to restart your PC after installing it before you can change that setting. So keep in iGPU mode on until you change the startup mode to NVIDIA. Then restart and switch the MUX to discrete.

Also, optimus-manager-qt will conflict with garuda-nvidia-prime-config

I use the same program (and an old build of superGFXctl, you don’t need that) to change graphics processor.

I tried what you suggested but this time after switching to nvidia, on reboot it still remains on integrated also if i switch to nvidia and on reboot set it to discrete graphics from bios I get directly a black screen unlike last time where was a sddm login screen. Below i enlisted the log when i use optimus-manager

optimus-manager --switch nvidia

Unfortunately, that’s the limit of my knowledge.

EDIT:
Try this then maybe?
I tried this before but it didn’t work for me. It might work for you though.
