Blackscreen after boot, nvidia fedora 41. Was working until I did post Fedora Install Guide

Fedora 41 on my XPS 16 has been great. I am not sure what I did but things were working fine in kernel-6.11.11 until I went throught the post Fedora install guide here: GitHub - devangshekhawat/Fedora-41-Post-Install-Guide: Things to do after installing Fedora 41

When I rebooted it went to black screen. I still had my older 6.11.10 kernel and it works fine. Waited for 6.11.12 that came out today and yep black screen as well. I’m guessing some sort of nvidia issue but everything was working just fine and 6.11.10 is still good with nvidia drivers an wayland.

Actually don’t think those logs mean much, I get the same logs in 6.10.10 and everything is working. Im at a loss and afraid kernel updates are just going to be broken for me. Is there anything I should try?

This ended up being a bug in the kernel due to ipu6 webcam. Kernel 6.12.5 has fixed the issue.
