HELP! Zorin OS is just showing a black screen

Hi! When I start the laptop everything is normal, every logo shows, after the Zorin logo it shows ZORIN text, after that I see the taskbar for 1 second, then it's just a black screen. I can see & move the cursor.
I can't access the Recovery menu using left shift.
I don't have a stick to reinstall.

maybe this thread can help
seems a kernel issue
