I also had this, but was able to pinpoint the issue when I looked which automation was disabled in automation overview and what the log tells you. Unfortunately the error was mentioning an error but not explicitly which automation was failing, that could be an improvement.
Again thanks for the reply. How do I open the command line?
Some of my automations seems to be working but I cannot open the automations page/editor.
The configuration error notification has now disappeared and there appears to be no log file errors relating to automations, I have tried deleting my entire automations yaml file but still no joy.
ok I got the terminal working and I have ran the core check, after it was complete it just said Done which I am assuming means no errors were found?
I’m really struggling with this.
I have found the cause of the notification. HA now has an issue with one particular automation and doesn’t like the time format in the yaml. For now I have removed the automation from the yaml file. This solves the notification issue but not the bigger issue of the automations feature not opening.
