Has anyone here created a bootable USB installer for Ventura that works with the latest M2 Macs, and if so, how did you do it?

The following is what I tried and its not working. I am trying to create a bootable installer for M2 Mac Studio with the latest Mac OS (13.4.1). First, I realize there are two builds for this OS, as indicated at https://mrmacintosh.com/macos-ventura-13-full-installer-database-download-directly-from-apple/

I downloaded the correct build 22F2083 from his page, the one indicated “for New WWDC Macs Only”. I run the resulting pkg file and it installs the “Install macOS Ventura” app into /Applications. I then use the terminal command

sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/InstallVentura

to try to make my thumb drive named “InstallVentura” into a bootable installer. The issue is that I get the error

Making disk bootable...
Failed to extract AssetData/boot/Firmware/Manifests/InstallerBoot/* from update bundle
The bless of the installer disk failed.

I tried this both on the Mac Studio and on another Mac and I get the same result. How do I fix this? Is there something wrong with this build that it will not convert into a USB installer?

Thanks
