MQTT fails after update hass 4.3

Hi, is it just me or have more people trouble after the latest hass upgrade. My solarpanels communicate by MQTT and it didnt work anymore after the update. Put my (full)snapshot back from 5 days ago and it runs fine again.

Did you check if you are receiving anything under the solarpanel’s mqtt topic in the mqtt integration listening function?

It cant listen anymore. after startup i will still connect my homeassistant itself but it does nothing anymore with the logins i created for sems, not even trying to login. after downgrade i can see the login again for sems and it works again.
