Sometimes a Kernel Update can cause problems, and you might have to select an earlier one to boot.

To remove the latest kernel first find out what it is with: 

dnf list installed kernel

Now select the kernel you want to remove, it'll be something like "5.14.0-503.14.1.el9_5" and remove it with

dnf remove kernel-5.14.0-503.16.1.el9_5 kernel-core-5.14.0-503.16.1.el9_5 kernel-modules-5.14.0-503.16.1.el9_5

Finally we must update GRUB with

grub2-mkconfig -o /boot/grub2/grub.cfg

Now reboot, and check.
