Thinkpad will not wake up from suspend

Hello, I am making this post after trying everything I could think of. I have 2 laptops (Thinkpad T480 and T580) that will occasionally hang when waking up from suspend. I have seen some of the forum posts about this issue, and have tried the fixes in these posts to no avail.

Symptom:
On my T580 after ~2 months of flawless operation (June to August), started to freeze occasionally when waking up from suspend. The "mute" key led would light up as expected (I have the laptop muted), but the power led is still in a slow breathing state, indicating the laptop thinks it's still sleeping. The cpu would get hot to the point that the fan will kick on, screen is off and the system will not go back to sleep after closing the lid again. The only way to recover is hard reset. The same thing happens on my T480 (same boot drive).

This is a sample of what the journal look like after the crash happened:

This issue first happened on August 26, and it would only happen intermittently. I applied the fix from this: https://bbs.archlinux.org/viewtopic.php?id=296954, and it seemed to solve the issue for about 2 weeks before coming back earlier this week. I switched from my T580 to my T480 thinking it's a hardware issue with the T580, but the same issue happened. Using the linux-lts kernel also did not fix the issue.

I also doubt that systemd is the problem here, the logs show that I upgraded systemd from 255.7-1 to 256.1-1 on July 4, and this problem only started last month. To further test this, I have downgraded systemd, systemd-libs, and systemd-sysvcompat from 256 to 255 but the problem still occurs on both laptops. If anyone can give me tips on what's wrong or possibly how to get more detailed logs in the journal about the crash it would be greatly appreciated!

My setup:
i7-8550U (both laptops)
Both laptops have almost the latest BIOS, both have had extensive run time on this same boot drive without issue.
2x16GB Crucial ram (passed memtest)
Running sway (1:1.9-5) with swaylock (1.8.0-1)
linux 6.10.10
linux-firmware 20240909.552ed9b8-1
intel-ucode 20240910-1
systemd 256.6-1
