A slightly neater way:

use 5.37.9;
no warnings qw( experimental );
use feature qw( class defer );
use builtins qw( true false );

class No::New {
    use Carp;

    my $allow_construction = false;

    ADJUST {
        croak "Directly calling @{[ __PACKAGE__ ]}->new is forbidden"
            unless $allow_construction;
    }

    sub create {
        my $class = shift;
        $allow_construction = true;
        defer { $allow_construction = false };
        return $class->new;
    }

    method text {
        "Congratulations!";
    }
}

say No::New->create->text;

(Note: I haven't actually tried this as the most recent Perl I have installed is 5.37.2.)
