Yesterday (July 3 '22) everything on Fedora 35 worked fine including my Nvidia 3080 GPU. This morning (July 4 '22) I ran dnf update and suddenly booting produced the message NVIDIA kernel module missing. I tried starting Blender which uses the GPU heavily and it hung during start. New kernel is 5.18.9-100.fc35.x86_64. Rebooting with the old kernel, 5.18.7-100.fc35.x86_64, restored access to the GPU.
You didn’t mention how you installed the driver but you might try booting from the latest kernel and reinstalling the driver so it will build with the latest kernel.
