This night, all my devices working on the mqtt broker are not working anymore.

The app states “this app has stopped unexpected”

There is no log.

I tried to restart homey / restart mqtt / reinstall mqtt

Need help urgently

homey 7.4-rc 22

FWIW, if you’re running experimental Homey firmware you can expect these things to happen.
