Z-Wave JS UI inclusion not working

I try to include a new z-wave device and start inclusion from z-wave js ui. It shows me a strange status … it is starting and stopped at the same time (schroedingers z-wave):

All other devices were included prior installing z-wave js ui, so i never did it using z-wave js ui …

I know, the new device is working, because i successfully included it into my old devolo home control and removed it after the test.

I can see the start of the inclusion in the logs, but i cannot see an error:

No idea, what changed today. I already restated anything yesrerday with no success. Today it was working:

It would still be interesting to know why it didn’t work yesterday and what you could do besides waiting and hoping it works the next day.
