More Info
This bug disappears after running nvidia-bug-report.sh for some reason, CUDA works again after running nvidia-bug-report.sh.
Edit: After more research I found out that running nvidia-settings as root somehow fixes the problem.
Edit 2: Loading the nvidia-uvm module though modprobe nvidia-uvm fixes this issue
