That confirn I think that you have both the rpmfusion and the nvidia
(cuda-fedora37-x86_64) repositories installed since cuda-fedora37-x86_64 is
using dnf.modularity.

What gives on your machine: dnf repolist | grep -E 'cuda|rpmfusion' ?

If you have both you should obtain something like:

cuda-fedora37-x86_64           cuda-fedora37-x86_64
rpmfusion-free                 RPM Fusion for Fedora 38 - Free
rpmfusion-free-updates         RPM Fusion for Fedora 38 - Free - Updates
rpmfusion-nonfree              RPM Fusion for Fedora 38 - Nonfree
rpmfusion-nonfree-updates      RPM Fusion for Fedora 38 - Nonfree - Updates

This shows that the nvidia kernel modules has been left even after removing
all the nvidia RPMs.

What gives: dkms status

xorg-x11-drv-nvidia-cuda comes from rpmfusion and only provides the cuda
driver, not the whole cuda software. If this is sufficient for BOINC, using
only the rpmfusion repository will work and will be simpler to manage.
