OnePlus 8 Pro additional partition required but lacks expected images

Update: I used the method shown here to create my own dtbo and vbmeta img files.

I followed the install instructions exactly and slowly and carefully.

At the end of the flash I receive the following message

E:\Downloads\_android\platform-tools>adb sideload e-1.19.1-r-20240110372391-stable-instantnoodlep.zip
serving: 'e-1.19.1-r-20240110372391-stable-instantnoodlep.zip'  (~47%)    adb: failed to read command: No error

The device showed the attached image.

Now, the device only boots to the bootloader but no OS. It will not boot to recovery ¯_(ツ)_/¯ any ideas?
