The discover issue is a a new issue and is being discussed here
It’s broken in both F44 and F45.
I’m not sure what’s causing the conflict the the nvidia drivers.
You can try doing sudo dnf upgrade --refresh --allowerasing
Fedora 45 is the current development branch (rawhide) so unless you’re comfortable with things breaking you should probably re-install f44.
