You have hybrid graphics:
Graphics:
Device-1: NVIDIA GA106M [GeForce RTX 3060 Mobile / Max-Q]
vendor: Hewlett-Packard driver: nvidia v: 520.56.06 arch: Ampere pcie:
speed: 5 GT/s lanes: 8 ports: active: none empty: DP-1,HDMI-A-1
bus-ID: 01:00.0 chip-ID: 10de:2520
Device-2: AMD Cezanne vendor: Hewlett-Packard driver: amdgpu v: kernel
arch: GCN-5.1 pcie: speed: 8 GT/s lanes: 16 ports: active: eDP-1
empty: DP-2 bus-ID: 07:00.0 chip-ID: 1002:1638 temp: 46.0 C
Device-3: Chicony HP Wide Vision HD Camera type: USB driver: uvcvideo
bus-ID: 1-3:2 chip-ID: 04f2:b735
Display: x11 server: X.Org v: 21.1.4 with: Xwayland v: 22.1.4
compositor: gnome-shell driver: X: loaded: amdgpu,nvidia dri: radeonsi

Screen-1: 0 s-res: 1920x1080 s-dpi: 96
Monitor-1: eDP-1 mapped: eDP-1-0 model: BOE Display 0x09f2 res: 1920x1080
dpi: 137 diag: 407mm (16")
OpenGL: renderer: NVIDIA GeForce RTX 3060 Laptop GPU/PCIe/SSE2 v: 4.6.0
NVIDIA 520.56.06 direct render: Yes
So if I am reading the /lib/udev/rules.d/61-gdm.rules correctly, it says:
# If this is a hybrid graphics laptop with vendor nvidia driver, disable wayland
LABEL="gdm_hybrid_nvidia_laptop_check"
TEST!="/run/udev/gdm-machine-is-laptop", GOTO="gdm_hybrid_nvidia_laptop_check_end"
TEST!="/run/udev/gdm-machine-has-hybrid-graphics", GOTO="gdm_hybrid_nvidia_laptop_check_end"
TEST!="/run/udev/gdm-machine-has-vendor-nvidia-driver", GOTO="gdm_hybrid_nvidia_laptop_check_end"
GOTO="gdm_disable_wayland"
LABEL="gdm_hybrid_nvidia_laptop_check_end"
So it looks like Wayland is disabled by default with proprietary nvidia driver.
Again, I don’t have experience with hybrid graphics.
You might need a “special” setup to make this work.
Please wait for forum members with experience on running GNOME-Wayland on hybrid graphics with Nvidia to come to assist.
I would check the arch wiki
https://wiki.archlinux.org/title/GDM#Wayland_and_the_proprietary_NVIDIA_driver
Seems it should default to Wayland as of 510 Nvidia driver. There are also some tips about how to enable it
And OP has:
NVIDIA 520.56.06
Maybe conflict with plasma… this post has been cryptic to begin with. Could be any other settings user changed or not.
I can agree with that post

Who hasn’t … 
Have you ever tried eos with gnome installation only? Did you then run Wayland? Or is this your first eos install and selected both plasma/gnome.
Any other system changes like config files edits?
Something I would try for the sake of testing is to install plasma-wayland-session as suggested further up in the thread and check if that would give an option to log into a Wayland session on Plasma.

You could try sddm instead of gdm as well
