Nvidia gpu not detected

For some reason my computer does not detect my NVIDIA gpu anymore… When I run nvidia-smi i get: 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 am running ubuntu 20.04. Please, can someone help me with this?

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
