Can confirm I'm also seeing this. I'm able to recover by installing the 23.02.2 linux-image-current-meson64 and linux-dtb-current-meson64 packages from /var/cache/apt/archives.
From what I can tell it's installing the modules for 6.1.50 in /lib/modules but is somehow still booting 6.1.11
/boot/uImage isn't getting updated
$ strings /boot/uImage | grep "Linux version"

I can confirm that running the following command manually gets the device back into a working state
$ mkimage -A arm64 -O linux -T kernel -C none -a 0x1080000 -e 0x1080000 -n Linux -d /boot/vmlinuz-6.1.50-current-meson64 /boot/uImage
