no such file or directory: /local/share/kscreen
Actually also:
no such file or directory: /local/share
I just relized i may fked it up with accidentally
mv local/share/kscreen local/share/ kscreen.bak
with I space in between
the kscreen folder is in your home directory:
/home/.local/share/kscreen
no such file or directory: /home/.local/share
I think not anymore 
Ok, wait… Sorry, now get it 
It’s in $HOME/.local/share
Yes, thanks, I also just catched myself in making this thought mistake while being already in the home folder.

nothing suspicious in the packages…
you can remove these packages, they are dead meat - they are not related to your issue:
electron12 - if you are using it install the bin version
etcher

do you have a timeshift backup?
do you have home on separate partition?
Both screens are set 100% scale.
No, i don’t 
Also not, looking back I wish I would have… Most of my data is stored on a separate partition though, but not the home folder.

nothing suspicious …
we could try rebuilding aur packages, this may help…
did you remove these packages?:
if yes, post output from:
inxi -A
it looks like you have both pulse and pipewire running
Done : sudo pacman -R electron12 etcher gnome-icon-theme gnome-icon-theme-symbolic manjaro-documentation-en manjaro-firmware
Audio:
Device-1: NVIDIA GA104 High Definition Audio driver: snd_hda_intel
Device-2: AMD ACP/ACP3X/ACP6x Audio Coprocessor driver: N/A
Device-3: AMD Family 17h/19h HD Audio driver: snd_hda_intel
Device-4: SteelSeries ApS Arctis 9 type: USB
driver: hid-generic,snd-usb-audio,usbhid
Sound API: ALSA v: k5.15.76-1-MANJARO running: yes
Sound Server-1: PulseAudio v: 16.1 running: yes
Sound Server-2: PipeWire v: 0.3.59 running: yes
PS: Probably going to answer later today again, thanks so far for your help!
ok so lets switch to pipewire:
pamac install manjaro-pipewire wireplumber
this will give you pulse dependency issues, so remove them first, then run the command again…
then remove this:
pamac remove pulseeffects-legacy
and these packages that could be related to your issue:
pamac remove lightly-qt latte-dock-git
(you can install them afterwards)
reboot and see if it helped…
if not rebuild the aur packages:
pamac build $(pamac list -qm)
this could take ages…
when its done reboot …
Did all that, still not starting the desktop 
Feels so weird, as over startx everything works 100% normal, just not with the normal boot.
have no idea what the issue could be…
remove the nvidia and try if you can boot on open source drivers:
sudo mhwd -r pci video-nvidia-470xx
reboot
so install the nvidia ones from tty:
sudo mhwd -a pci nonfree 0300
reboot
After installing it, it directly booted into the desktop. But after reboot, same story.
