I installed arch last night using archinstall and chose the kde version. Have secureboot and tpm disabled because i saw a few posts mention it might help.
Other troubleshooting ive tried is booting off a usb and running mkinitcpio -P and reinstalling gpu drivers (i915), ran grub-mkconfig -o /boot/grub/grub.cfg.
The system was fully working, managed to do updates with fwupd as well.
Last thing i was doing before the crash was trying to change my sddm theme, I chose one of the presets and change the wallpaper. Logged out and it hadnt change so i rebooted the laptop. Have been crashing since. Any ideas?
