Problem

I have seen many similar questions in this forum, and I have tried many of the solutions proposed, however nothing seems to work :c

I was trying to install CUDA from the CUDA installation guide. This process asks to install the CUDA toolkit and during this process I had to update the nvidia drivers.

I tried updating my nvidia drivers from the website for my configuration. I have an NVIDIA RTX4000 ADA, and I'm using a lunix computer with Ubuntu 22.04. On the website it says that the latest driver is the nvidia driver-550. I dowloaded the file and tried running the installation from terminal by running:./NVIDIA-Linux-x86_64-550.67.run. However there was a warning prompt saying that I should do the update from the ubuntu application "Software & updates". So I cancelled the updates and I went to this app and selected the drivers that said recommended. I reboot my pc and now whenever I try running nvidia-smi I get the following error:

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

I tried reinstalling the drivers and I broke the setup even further or something because now when I open "Software & updates" I don't even get a recommended option...

I'm sorry I am not very tech savvy, should I restore my computer from factory settings or can this problem be fixed?

sudo dkms statusnvidia/550.54.14, 6.1.0-1036-oem, x86_64: installed

What I have tried (Update)

Tried reinstalling the drivers in many ways and even from a root shell ( Nvidia Driver Broken on Update - Unable to Reinstall ) . Tried sudo ubuntu-drivers autoinstall and sudo reboot.

I feel like I am trying random stuff at this point because I don't really know what is broken in the first place...
