error when i try to create macos installer

error when i try to create macos installer

my thoughts are its because im not connected to the internet to be able to download a macos installer.

ive tried searching the internet but to no avail, ive tried moving files from /Library/Extensions suggested from another post with the same issue that didnt help.

i think it may be because i havent installed a post-install root patch but the box is fully greyed out so its not giving me an option to.

any help would be greatly appreciated.
