Did you use Wi-Fi to do the download? If so, the file has likely gotten corrupted and therefore can't load. Wi-Fi is too slow for these very large files, which causes the corruption to occur. Retry using a wired Ethernet connection and all should go well. If that is not available, you may have to do multiple downloads to get one that will work.

What is the exact model of this Mac? You can get this information by entering the system serial number on the check coverage page here (please don't post the serial number on the forum since it is considered personal information):

Also, what version of macOS is that USB installer and how did you create it exactly?
