Journey snap not launching after first time



Ubuntu 19.04, snapd 2.40+19.04, snap ‘journey’ 2.13.1

The journey snap stopped working for me a release or three ago (sorry, I did not report it, figured I did something). If I remove the snap, then reinstall it, I can get it to work once, then when I try to restart it, it exits with an error code value of 1, with no output. I see nothing in the system logs, journalctl, or dmesg.

I thought it might be my WM (i3), but I can reproduce it under GNOME, and I have reproduced it on two machines, both Ubuntu 19.04.

Pointers to any snap debugging guides or suggestions on what to look for would be great.
