Boot anim freeze post update to Android 15, Nothing OS 1.5

[tux3]

Updated magisk app to 28.1, installed Nothing OS 1.5 (Android 15), and installed the new Magisk 28102 to A/B slot.
Next boot froze on boot animation.

Disabling modules did not help, logs below are after removing modules and rebooting.
Recovered with magisk --stop and setprop ctl.restart zygote.

dmesg during frozen boot: dmesg.txt

Now, after a Google Play system update and a few more reboots, it stopped freezing on boot. Magisk app reported Zygisk: No, Ramdisk: Yes, and I had root.
I did a direct install again, hoping to clean up any leftover weirdness, still boots OK, root is working.

It sorted itself out for mysterious reasons, but there is still an issue somewhere that made it freeze post-update and required manual intervention, so reporting for your consideration.
