Can't get past Plymouth, Recovery says my password is invalid

I messed up really bad. I wanted to change my greeter to COSMIC’s, following these instructions. Now I can’t get past Plymouth because it hangs like this:

20250416_231136
20250416_2311361920×1920 342 KB

And if I try to go into Recovery mode, it denies my password as “login incorrect”

I wanted to change my display manager because GDM doesn’t support Xorg at the moment, SSDM doesn’t look that nice, and LightDM has broken text rendering.

I have a USB for Fedora 40 with me. What files do I edit to get myself out of this situation?

This should be fixed soon:
FEDORA-2025-36e1759b84 — enhancement update for gdm — Fedora Updates System
You can already install the RPM from Koji.

Boot like this and then revert the changes:
How to Reset the root Password :: Fedora Docs

systemctl disable greetd.service
systemctl disable sddm.service
systemctl enable gdm.service
touch /.autorelabel
echo s > /proc/sysrq-trigger
echo u > /proc/sysrq-trigger
echo b > /proc/sysrq-trigger

Thank you! Changing the password isn’t working though
I know it isn’t a keyboard layout issue because I tried typing into a text field where it would actually show what I am typing and I am typing the same thing
What do I do?
Edit: To clarify, it updates successfully, but it still denies me access on any of the TTYs that I try
Update: I missed a step. Now waiting for relabelling to happen
