Unrecorded and unclogged crashes to power off

I attempted to activate AMD’s provided overclocking feature in the UEFI. This caused a kernel panic. I attempted to restore UEFI defaults. This solved the kernel panic, but the operating system no longer functions.
The current situation is as follows: I press the power key, enter the passphrase for my drives, boot cachyos. (Removing Plymouth solved an error here). I can successfully reach password entry, and sometimes do things on the desktop, but the system then turns itself off (screen black, LED on the power button goes dark. I don’t even know if this is a recognized crash mode.)
If I enter TTY immediately, the crash is avoided.
