This error message in general means that the app tried to talk to some
other process over dbus, which by default is prohibited for sandboxed
apps like flatpak. You need to figure out what its talking too, and
give it access to that.

However, given the particular error message "Failed to register", my
guess is that its not really talking to another instance, but to the
bus itself, trying to register itself with a know name. In flatpak, by
default an application can only own a name on the bus with the
application ID as the name. In you case that would be
"org.christoffen.Logogenerator3", but maybe the app is using a
different name.

Can you run the app outside the sandbox (or with flatpak run --
socket=session-bus) while at the same time running 
"dbus-monitor --session". Then you should be able to see what the app
does on dbus.
