Ubuntu 20.04 blocked after upgrading nvidia drivers

This didn’t solve the issue. However I solved the issue by installing an old driver, by following this: *Bug* 470.42.01-1 dGPU can not be initialized - #13 by Kanguru007

These are the commands I entered:

#remove the current NVIDIA driver

sudo apt remove nvidia*
sudo reboot now

#disable the noveau driver

sudo echo "blacklist nouveau" >  /etc/modprobe.d/blacklist-nvidia-nouveau.conf
sudo echo "options nouveau modeset=0" >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf
sudo update-initramfs -u
sudo reboot now

#install NVIDIA 460.84 driver
#downloaded from https://www.nvidia.com/Download/Find.aspx?lang=en-us

chmod +x NVIDIA-Linux-x86_64-460.84.run
sudo ./NVIDIA-Linux-x86_64-460.84.run
sudo reboot now

In the end, my configuration was:
Ubuntu: 20.04.2 LTS
Kernel: 5.13.0-30-generic
Nvidia driver: 460.84
