This issue is easy to replicate in any clean install of Ubuntu 19.10. For example,
$ sudo apt install hexchat
$ hexchat
That would allow you to trouble shoot on an development system.
Happy to provide a full 'journalctl -b 0' log if requested, but probably more useful to generate on a development machine. Here are the last few lines of mine, the "Failed: Could not get window list" sounds promising...
