It sounds like you may have interrupted the build of the nvidia drivers.

Try
sudo akmods --rebuild --force --kernels 6.17.10-300.fc43.x86_64to ensure all akmod modules have been rebuilt for the new kernel then reboot.
The new module you are trying to use appears that it will require a rebuild with every kernel update, though the steps in the repo link you provided appear to need nothing more than the final command make install (in the build directory & after booting into the newer kernel) to perform the upgrade.
The steps do not appear to use dkms with what you provided so the discussion topic linked would not apply and manual updates would probably be necessary.
I do note though that it appears to build the module that is then stored in the firmware area and is available to auto-load from there. That means that the only thing that may overwrite it would be the monthly update to system firmware and rebuilding could be scheduled to coincide with those updates (probably not dependent upon kernel updates).
