Basic Rule trigger/action problems or device problems?

I'm having similiar behaviour with my C8 pro since the last update. Some automation won't trigger or if triggered devices won't turn on or off.
Also zigbee devices are getting a command to change state but are not responding. It's looks like the zigbee network or radio is not working properly - this all started after the last update. Before the update everything worked flawlessly...

I don't know what to do... I am afraid to rollback (it can make the hub to work worse then now), I don't know if the next verion will fix something, I don't know if I need to do something with the zigbee radio (change frequency or similar)...

PLEASE HELP....

you can roll back it should be fine from what I am told.
