Keep getting error

I am keep getting this error when I try to create Sonoma installer on my USB-stick.

I am working on a MacbookPro 15 inch late 2013 - Mac OS catalina 10.15.7

This is what I already did: - bought new 64gb usb - gave oclp full disk access - tried deformatting usb in MS-DOS (FAT) and Mac OS (journaled) - tried this step on a newer IMac

Is there something that I am missing? Thanks for helping me
