on Ubuntu 20.04, kernel 5.14.0-1034-oem I had nvidia-drivers running and had no issues. After upgrading or rebooting it was suddenly not working anymore. I have a Dell PC and an GeForce GTX 1660 SUPER.
$ nvidia-smi NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

When starting, I have multiple messages which i googled but did not get further:

Stuff i tried
I tried many different solutions but nothing worked:
Reinstalling all drivers → No effect
sudo apt purge *nvidia* sudo apt purge '^nvidia-.*' sudo apt purge '^libnvidia-.*' sudo apt purge '^cuda-.*' sudo apt-get install nvidia-driver-470 sudo reboot
Tried both driver-470 & driver-510
Switched off Secure Boot in Bios → No effect
Blacklisting modules → No effect
blacklist nvidiafb blacklist nouveau
Switching to 5.10-oem Kernel → Led to not being able to boot anymore.
Prime selecting nvidia → No effect
sudo prime-select nvidia

Thanks for your help!
