The Windows Insider builds are development versions that can block normal upgrades. When you try to install a standard Windows 11 Pro license from an Insider build, the upgrade process often fails because the installer can't properly transition between these different update "channels." The 27% mark typically corresponds to the "checking for updates" phase of installation.
