Getting this error message when trying to create USB installer. My downloaded MacOS is 12.6.3.
Couldn't mount dmg /Applications/Install macOS Monterey.app/Contents/SharedSupport/SharedSupport.dmg (error code 112)/Applications/Install macOS Monterey.app does not appear to be a valid OS installer application. (253)

The error seemed to have stemmed from a corrupted macos installer download.Redownloading fixes it for me. Please close this issue. Thanks
