Having trouble creating a boot installer

I tried to run the Terminal installer script but I got this at the end:


Copying essential files...

Copying the macOS RecoveryOS...

Making disk bootable...

Failed to extract AssetData/boot/Firmware/Manifests/InstallerBoot/* from update bundle

The bless of the installer disk failed.



Does that mean the downloaded installer is corrupt, and I need to redownload?


Thanks very much.


PS the boot jump drive Is completely blank. Nothing written to it.

There is a known issue with creating bootable installer using macOS Sequoia.
