Getting stuck at ==> hyperv-iso: Waiting for SSH to become available.... while automating installation of ubuntu 22.04.4 live server

Hi am new to devops hence please help me out.While writing the below command

    packer build -force packer.json

I am trying to run a config file which should automatically install ubuntu in a vm.

packer.json

{"variables": {"vm_name": "ubuntu-live","cpu": "4","ram_size": "8192","disk_size": "81920","hyperv_switchname": "ExternalNetwork","username": "vagrant123","password": "vagrant123","iso_url": "https://example.net/OS/Ubuntu/ubuntu-22.04.4-live-server-amd64.iso", #the link has been changed"iso_checksum": "125022addbe20d3a9e3b71e04653f67b","memory": "2048","cpus": "2","ssh_username": "vagrant123","ssh_password": "vagrant123","packer_temp_directory": "C:/Users/Def/PackerTemp"    },"builders": [      {"vm_name": "{{user `vm_name`}}","type": "hyperv-iso","disk_size": "{{user `disk_size`}}","guest_additions_mode": "disable","iso_url": "{{user `iso_url`}}","iso_checksum": "{{user `iso_checksum`}}","communicator": "ssh","ssh_username": "{{user `username`}}","ssh_password": "{{user `password`}}","ssh_port": 22,"ssh_timeout": "10m","boot_wait": "5s","http_directory": "linux/ubuntu/http/","http_port_min": 8000,"http_port_max": 8000,"boot_command": ["<esc><wait><esc><wait><esc><wait>","<c><wait><bs>","set gfxpayload=keep<enter>","linux /casper/vmlinuz autoinstall ds=nocloud-net;s=http://{{.HTTPIP}}:{{.HTTPPort}}/ auto<enter>","initrd /casper/initrd<enter>","boot<enter>"        ],"shutdown_command": "echo {{user `password`}} | sudo -S -E shutdown -P now","memory": "{{user `ram_size`}}","cpus": "{{user `cpu`}}","generation": 2,"switch_name": "{{user `hyperv_switchname`}}","enable_secure_boot": false,"output_directory": "./BaseVM","temp_path": "{{user `packer_temp_directory`}}"    }    ],"provisioners": [      {"type": "shell","inline": ["echo 'Provisioning VM...'"        ]      }    ]  }

In the VM I can see that the screen is stuck at language select during the installation.

I have tried adding preseed.cfg.

I was expecting it to be installed but instead it is stuck at

and a vm screen with select language.
