GUI doesn't show up

Hi, I have a problem with booting.
My pc turned off due to low battery and when I turn it on again, after showing the Zorin logo the screen goes black and the tty option shows up asking me for username and password. I can't get the normal desktop back, I tried with lightdm and didn't work, also with system recovery and network manager restart but still nothing.
Hope there's a way to fix it. My os version is 15.3.

What does it say if you type;

startx
