Can't create a macOS Sequoia bootable USB

Hello.

I'm on a MacBook Pro M3 Max with macOS Sonoma installed.

I have a 32Gbs USB and downloaded macOS Sequoia from the Mac App Store.

When the download ended and right before the installation window opens, I receive a message saying that macOS Sequoia installer couldn't be found. I actually have the file on my Applications folder and it weights 58 MBs?!?!?!

I tried using the following command (taken from the Apple Website):

sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

But my Terminal tells me that '/Applications/Install macOS Sequoia.app does not appear to be a valid OS installer application.'

Why is this happening? Basically I can't Install macOS Sequoia nor can I create a bootable USB drive.

Is this happening to anyone else? How can I solve this?

Thank you.

MacBook Pro 14″, macOS 14.7

The Full Version of macOS 15 Sequoia Installer Application is 14.54 GB

see below

What you have appears to a " Stub " which has just enough of Sequoia on it

So that when you launch this Stub, it will call back to the Apple Servers and pull down all the remaining elements of Sequoia

May it be suggested to delete the Stub, if you want to create a Bootable Installer

The use the Terminal Command below to Pull the Full 14.54 GB

softwareupdate --fetch-full-installer --full-installer-version 15.0

I can verify it did work and yes successfully pulled the Full Version

How can do this on a Windows PC?
