PSE 2023 doesn't run on Windows 11 unless manually told to open as Administrator at every start up. This is a rather recent development.  Windows update?  At first it opened the Organizer, but I couldn't send pictures to the Editor. After some searching I succeeded to get around this by manually tick a box to open as
Administrator.  I first have to start up  the Editor this way and than the Organizer like that too.

Try uninstalling and then install as an Administrator.
