CUDA 12 broken on my system (possibly NVIDIA open kernel module?)

ILL version mismatch:

The open-source kernel-mode driver works with the same firmware and the same user-mode stacks such as CUDA, OpenGL, and Vulkan. However, all components of the driver stack must match versions within a release. For instance, you cannot take a release of the source code, build, and run it with the user-mode stack from a previous or future release.
