ARM64 autoinstall crashes at netplan apply

[Aliseo Purpura-Pontoniere]

Hello, I'm trying to run a completely non-interactive autoinstall of ARM64 Ubuntu Server on a VM hosted on an x64 machine. I have no issues doing this with an x64 Ubuntu Server ISO and qemu-system-x86_64, but when I try to do it with an ARM image and qemu-system-aarch64, it always crashes towards the beginning of the autoinstall process with:

An error occurred. Press enter to start a shell

I've tried many different variations of the qemu command, but this is the base I started with:

qemu-system-aarch64 -M virt -cpu cortex-a72 -smp 8 \
-bios /usr/share/qemu-efi-aarch64/QEMU_EFI.fd \
-nographic \
-m 65535 \
-vnc :2 \
-net nic -net user \
-drive file=/home/alip/images/ubuntu22armserver.img,format=raw,if=virtio \
-drive file=/home/alip/isos/autoinstall.iso,format=raw,if=virtio \
-cdrom /home/alip/isos/ubuntu-22.04.3-live-server-arm64.iso \
-kernel /isomount/casper/vmlinuz \
-initrd /isomount/casper/initrd \
-append 'console=ttyS0 autoinstall'

 - ubuntu22armserver.img is the blank image file I'm installing to, made with 'truncate -s 10G ubuntu22armserver.img'. I've also tried using 'qemu-img create ubuntu22armserver.img 10G'
 - autoinstall.iso contains the blank meta-data file and the user-data file with the autoinstall configuration, created with 'cloud-localds ./autoinstall.iso ./user-data ./meta-data'
 - the ubuntu-22.04.3-live-server-arm64.iso is mounted at /isomount to provide kernel and initrd

Contents of the user-data autoinstall file:

#cloud-config
# autoinstall configuration file for Ubuntu/subiquity
autoinstall:

    locale: en_US.UTF-8
    keyboard:

Interactive installs with the above qemu command work without any problems. The installer is able to update itself, and mirror checks pass.

Crash file is attached. Please let me know if I can provide any more info.

Any help you could provide would be great. Is there a way to simply disable the network entirely during the install? Thanks in advance for your help.

I've tried running the above on an ARM platform with the same results

I've tried including 'netcfg/do_not_use_netplan=true' to the kernel cmdline with the same results
