Stuck at blinking under score after boot

Everything works fine, during boot as all those things gets loaded and suddenly all i see is that blinking cursor, i cant write anything. only change i made was to use sudo pacman -Syu to update the system and nothing else. I tried finding a solution online but they all mention driver problems with a specific graphics card but i have an i3 processor with intel graphics not a dedicated GPU.

I am writing this from a live usb of endevouros. I am able to mount my endevouros installated disk and chroot into that, but i have no idea how to fix it. kindly help.

if it helps i have budgie, gnome and i3wm installed although i mostly use i3wm

what is the exact error on the prompt ?
