change the SSD and retry (the same ssd in another machine may not trigger the same error btw, this is not unilateral process of elimination) - those windows updates do a lot of disk writes and a small miss there can screw up an entire install since it shuffles things around in preboot environment (moving them on disk) and that can corrupt things and prevent a new install in the same way.

You can also try to live boot into Ubuntu 25.04 arm64 since that iso has experimental snapdragon elite support and has some built-in drivers for storage and network - you can extract firmware from the windows drivers with qcom-firmware-extract - they recommend doing this from a windows partition which you should have (albeit possibly corrupted).

If that still fails - you have a ram issue as others have pointed out. I've had the exact same symptoms (hardware instability after windows update) and it was nvme ssd (an early samsung one) and ram, in both instances.

Not saying the windows update didn't also come with some junk firmware that got loaded into some of your devices, but that would be a distant diagnosis from ssd/ram (and many others would have seen the exact same thing during their update if it was that).
