Remember the Pi has an odd architecture and all the IO passes through the GPU. The GPU doesn't log human readable messages anywhere. There's a good chance the GPU did log a crash or failure, but only broadcoms engineers can see it.

Er, really, wow. I didn't know that. Can you point me at some more info for that? Surely the GPIOs don't go via the GPU.

It's a BCM2711, and the datasheet is NDA only - typical Broadcom!

The VideoCore (Broadcoms GPU) is the main processor on the thing, and the cluster of ARM cores that run Linux are more of a coprocessor which can only see some of RAM.
