Configuration yaml suddenly shows indentation errors where it didn't used to

Below is the top of the configuration yaml that I’ve been using for a while. During a recent update (not sure exactly which one) I started getting indentation errors from all of the !include lines below. There are no indentations on any of them and I cannot figure out why there is suddenly an issue. Any help will be greatly appreciated.

homeassistant:
# Configure a default setup of Home Assistant (frontend, api, etc)
name: home
unit_system: imperial
  
internal_url: "http://homeassistant.local:8123"

default_config:

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

It has always been:

homeassistant:
# Configure a default setup of Home Assistant (frontend, api, etc)
  name: home
  unit_system: imperial
  
  internal_url: "http://homeassistant.local:8123"

default_config:

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

so any idea why I would be getting indentation errors from these lines?

Because yours doesnt look like toms example. See the name:, unit_system: and internal_url: lines
