I’m guessing from your previous posts here: Lock screen crashes or freezes on KDE Rocky 9 - #6 by Yani and here: Warp Terminal How's had a go at it? you’ve been trying to use warp terminal and it’s AI to solve you problem and now it’s gone wrong? I would say you probably put way too much trust in the information that supposed AI terminal was giving you?
You probably need to remove everything from preempt=voluntary to the end of the line where it ends at amdgpu.gpu_recovery and then attempt to boot it, or use the rescue kernel that is also in the grub list to boot from.
