Configuration errors in HA Core

Update. I reinstalled last night’s backup and the errors persist. The problem is not the Core update.

My system:

Home Assistant 2023.3.6
Supervisor 2023.03.2
Operating System 9.5
Frontend 20230309.1 - latest

I updated the HA Core and got this error:
Any ideas? And what is SSDP?

Home Assistant Core

I ran the update of HA Core and got this error:
Error handling when_setup callback for frontend

10:11:56 AM – (ERROR) helpers/network.py - message first occurred at 10:11:56 AM and shows up 2 times

Check out

and maybe try add

# Example configuration.yaml entry
ssdp:

or

and double check that this exist:

`# Example configuration.yaml entry
default_config:

Not much but at least something to test.

Thanks. I do have default_config: in my configuration.yaml
So, still looking for any solutions. It isn’t stopping anything from working, but I really don’t like error messages.
