Hard crash using hardened kernel

Hi, I have been using the hardened kernel for about a year now without issues. In the last couple of weeks, I've begun having hard crashes intermittently. When I say hard crash, I mean the system becomes totally unresponsive, the last audio sound that was played is looped, and my capslock key light turns on and stays on. I cannot input any keyboard or mouse commands and I am forced to do a hard reset by holding the power button. They occur somewhat randomly, often when I'm watching a video using mpv or youtube, sometimes on resuming from sleep, some times running some scientific computing code (which hogs resources, but has been run 100s of times before without issue). There are no peripherals plugged into this laptop aside from the usb-c power cord. A couple days ago, it crashed in the middle of a kernel update and I had to chroot and clean everything up. I just switched to the regular kernel a few hours ago and it seems to be stable.

Things I've done:
- Checked system logs with journalctl and kernel logs with dmesg, both unrevealing.
- Ran hardware diagnostics, including memtest86+, built-in BIOS-level CPU/GPU/RAM/SSD/screen/battery diagnostics, all clean.
- Tried disabling hardware acceleration since I first noticed it tied to video playback, no change.

My system:

XPS 15 9520 (2022 model)
CPU: Intel i7 12700H
GPU: integrated + 3050 Ti
RAM: 32gb, with a swap file
SSDs: 2x samsung 1TB

Kernel: Linux-hardened 6.7.8
Nvidia driver: DKMS 550.54.14-4
File system: ext4 with LUKS encryption (also have secure boot/TPM auto-decrypting in case it's relevant)

I'd love to keep using the hardened kernel, would love any advice about what to try next.
