    Hi @Anthony Gribben-Lisle,

    You are using Windows 11, there is a known issue when you install sql server on Windows 11.

    Try one of the resolutions in this article.

    If this does not work, try to uninstall sql server clearly and re-install.

    1. Remove all SQL Server components from 'Programs and Features'
    2. Backup the registry
    3. Delete the following keys in regedit:

    --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

    --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer

    1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server
    2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server
    3. Reboot the machine

    Regards，
