I tried to recover from the last three backups that are available but same happens. I tried also to check the config files in YAML menu but it get stucked on the loading sign. I don’t know what else to try :frowning:

Is this always caused by a problem with scenes?

I am getting the same error, but I can’t see anything to do with scenes being the problem. Here is my YAML in case you can help?
