Hello,
I could manage to resolve the issue, the solution was to properly reinstall NVIDIA driver, when logged in with the new kernel. The dnf remove akmod-nvidia didn’t remove all driver components, I had to run dnf remove xorg-x11-drv-nvidia\* instead. (I realized, also in the driver’s documentation this is the suggested way to remove the driver.) After the driver was fully removed, reinstalling by dnf install akmod-nvidia did the trick.
I also upgraded to Fedora 36 then, which perfectly works with the NVIDIA driver after these steps.
