Can't start integration "automations" after upgrade

[larronni]

The problem

After upgrading to 2024.4 automaton can't start anymore...

"Setup failed for 'automation': Invalid config."

It looks like all automations are gone...?

Can't restart Home Assistant either, get this error when trying:

The system cannot restart because the configuration is not valid: Unexpected error calling config validator: 'int' object is not iterable

What version of Home Assistant Core has the issue?

2024.4.0

What was the last working version of Home Assistant Core?

What type of installation are you running?

I expect #114825 will fix this issue but its impossible to know without being provided a copy of your automations.yaml

[larronni]

Found the issue... It was related to an automation that used a Blueprint.. This caused all automations to fail, and also cased HA not to be able to reboot (config fail)... Do not know is this could be prevented somehow in the future....
