Modbus issue in config. yaml

HA Version 2025.1.3

I get an error when modbus gets activated in configuration yaml.

Pls see config yaml:

Loads default set of integrations. Do not remove.

default_config:

Load frontend themes from the themes folder

frontend:
themes: !include_dir_merge_named themes

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
modbus: !include modbus.yaml

homeassistant:
