Hello!
The first problem:
is self-explicative and it is under the attention of the development team. We might ask you for additional information, if possible please keep following this thread and thank you for your patience and testing.
It's expected and fine that CTRL-Z breaks the connection, because CTRL-Z STOPS the job, therefore OpenVPN or WireGuard can not keep the connection alive.
For a more comfortable environment with Eddie CLI, you can use screen or tmux - https://www.gnu.org/software/screen/ or https://www.howtogeek.com/671422/how-to-use-tmux-on-linux-and-why-its-better-than-screen/
They are both available in the Debian 11 repositories.
Kind regards
