Can’t access can’t delete network site

I created a new sub network on a WP multisite – but it has no super admin

it is listed under All Networks

but can’t access network admin dashboard /wp-admin/network/admin.php?page=networks lists the network, but there is no Admin – it is blank dash under Users

If I attempt to access the Network dashboard from the list it goes to login screen and my super admin credentials get “Sorry, you are not allowed to access this page.”

from Networks list I can’t delete the network “Cannot delete network with sites.”

the subsite dashboard is accessible through Network Dashboard > My Sites /wp-admin/my-sites.php – and it requires login and looks like a subsite dashboard

However it is not a ‘site’ in the Primary Sites list, I can’t find anywhere to delete it

I created a new network user with super admin privileges but it is not admin for the problem network

I tried editing wp-config with and without cookies configuration and other config constants

1) can I fix this by somehow adding a User with super admin ?
2) how can I delete the network ?

thanks
