BTW I am using Arch, have a NVIDIA GeForce GTX 1660 Ti Mobile, KDE with SDDM, laptop with internal screen and 2 external connected by USB-C.
Everything worked fine. Yesterday I did a full upgrade. Today the graphical boot failed, Playmouth Boot Screen could not be terminated.
I played around and found that the graphics will boot when I comment this line in /etc/X11/xorg.conf:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 530.41.03
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0"
.....
Section "Device"
Identifier "Device0"
# Driver "nvidia" #when commented graphical boot works with 1 Monitor
VendorName "NVIDIA Corporation"
BusID "PCI:1:0:0"
EndSection
.....
SubSection "Display"
Depth 24
EndSubSection
EndSection
So I guess that it is related to the NVIDIA driver
pacman -Q nvidia
nvidia 530.41.03-6 #different from mod. normal?
When I check the mod loaded:
modinfo $(modprobe --resolve-alias nvidia)
filename: /lib/modules/6.2.13-arch1-1/extramodules/nvidia.ko.xz
firmware: nvidia/530.41.03/gsp_tu10x.bin
firmware: nvidia/530.41.03/gsp_ga10x.bin #different from above. normal?
alias: char-major-195-*
version: 530.41.03
supported: external

Kernel log. I've noticed that some signature fails to load but no idea if this is the problem and if how to fix it: dmesg | grep nvidia

The problem is that I need the Nvidia driver for my external usbc screens. They are not working anymore for some unknown reason and I don't know how to proceed debugging. I am relative new in Linux. Any ideas how to continue?
UPDATE When I try to start the Boot screen from login shell i get this error:
kstart plasma-desktop
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
I've tried: Reinstalling: qt, nvidia related packages, plasma
