This rpm is not safe to use on f40

[RheaAyase]

Nuked all my drivers. As it is this repository can cause more harm than good, I suggest removing it unless you plan on maintaining it properly, as a copr package following all the packaging practices.

It has been built for use with Ublue or bluebuild. it worked on fedora well. I'm not maintaining the RPM any more it's kept more as an archive.

Nuking all your driver shouldn't be possible with a RPM unless it's meant to do so... you can look at the spec file and check by yourself that it just uses dkms. in the worst case it can prevent you from loading kernel modules so uninstalling it should fix your issue.
