Endeavour cannot boot

Hello Everyone!
I have a computer (TurboX flame u7-475) with Endeavour OS. I had some packages updates today and after a reboot, the system cannot boot. Everything is booted normally, it also says “Welcome to Endeavour”, but after this, the screen remains black and all you can see is a white cursor at the top (left side).
I tried to chroot and reinstall kernels as someone told me a year ago in another topic, but nothing happened (EndeavourOS)

Is there anything I could do repair my system, or even to transfer all my files to a USB and reinstall the Endeavour?

Thank you for your attention!
