Fix:

1. Reboot → GRUB menu → “Advanced options for Ubuntu” → choose an older kernel.

2.If the screen stays black after booting,press Ctrl + Alt + F3 to enter tty, then log in.

3. Run:

sudo apt remove --purge nvidia-*

sudo apt install nvidia-driver-550

sudo reboot

I’m not very familiar with NVIDIA drivers, so this might or might not work.
