I was using Rog custom kernel in my fedora workstation. During a regular update, boot screen shows Rog kernel failed to load and now unable to login.
I am able to get a command line from login page using ctrl+alt+F2.

Why do you need the rog kernel?
What is missing from the Fedora kernel that you need?
Likely the kernel has broken support for the GPU.
Maybe a mismatch between mesa and the kernel?
