Steps to reproduce:

1. Install Ubuntu Lunar or a flavor thereof onto physical hardware with a WiFi adapter. (I used Lubuntu Lunar.)
2. Connect to WiFi and install all updates.
3. Enable the Netplan Everywhere PPA and install the updated NetworkManager from it (further details at https://discourse.ubuntu.com/t/call-for-testing-networkmanager-yaml-settings/32420?u=arraybolt3)
4. When the installation finishes, run "sudo netplan get".

Expected result: Networking information related to the WiFi connection should appear in the "sudo netplan get" output.

Actual result: "sudo netplan get" returns the following:

    ** (process:4088): WARNING **: 12:41:41.394; Permissions for /etc/netplan/01-network-manager-all.yaml are too open. Netplan configuration should NOT be accessible by others.
    network:
      version: 2
      renderer: NetworkManager

End of output.

Additional information:

If I disconnect from WiFi, then delete my WiFi connection entirely in nmtui, and *then* reconnect to the same WiFi network, "sudo netplan get" returns the expected networking information.

This bug seems like it will probably cause unintended behavior after an upgrade from 23.04 (which uses normal NetworkManager) to 23.10 (which is supposed to be using the Netplan Everywhere NetworkManager).
