After a fresh install of a new system, using the Silverblue 42 install ISO, upon going through the initial setup process, after enabling *Third Party Repositories* and pressing *Next*, the app freezes. Reproducible: Always Steps to Reproduce: - Install Silverblue 42 on a bare-metal or VM, using the available ISO image. - After a successful installation, reboot. - After reboot, the Initial Setup (`gnome-initial-setup` component) starts. Navigate though the options pages. - When reaching the *Third Party Repositories* page, select the *Enable* option. Hit *Next*. Actual Results: The setup process hangs, and the *"Initial Setup" not responding* message appears, with the *Force Quit/Wait* options. The *Wait* option doesn't help. Expected Results: Next page appears, and the Setup process finishes successfully. Additional Information: - Workaround: User chooses to *Force Quit*, force reboots and runs the *Initial Setup* without third party repos enabled. - This issue does not replicate on the initial setup of a *Fedora Workstation 42* fresh install. - Used Silverblue ISO: v42-1.1. - Initially reported here: https://gitlab.com/fedora/ostree/sig/-/issues/74.
