NVIDIA GeForce RTX 4070 Max-Q / Mobile Graphics card not working drivers installed (Dell XPS Laptop)

I have a Dell XPS 19 running Fedora 38 with integrated Intel Graphics and a GeForce RTX 4070 Max-Q / Mobile. I installed the nvidia drivers with the instructions on this website:Download & Install Fedora 35 & GNOME 41 from USB Bootable Disk - LinuxCapable…-fedora-linux/

It worked for a short time but doesn’t anymore now the only thing I did since the install is running

sudo dnf update

If I run nvidia-smi now I get the following error message

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

And on nvidia-settings

ERROR: NVIDIA driver is not loaded

Did you ever figure this one out?

Thank you.
