Not responding after connecting to a hotpot Hidden Network

[Moshe Caspi]

Ubuntu 20.04.

Steps to reproduce:

1. Run gnome-control-center/Wi-Fi.
2. Connect to a Hidden Network (a hotspot in my case).
3. After connection, click the network settings.

What I expect to happen:

Get the connection information.

What happens:

After a few seconds, a box appears with the message: "Settings is not responding", and I have to Force Quit.

This happens only after the first time I run gnome-control-center and make the connection.

from syslog:

Thank you for your bug report and sorry for the lack of replies. Is that still an issue in the current package version?
