Help with script and broadlink

Configuration
1

I have 3 RM minis which are working ok.
This morning I wrote the following scripts which were working ok. (just reloaded scripts)

#script:
soundbar_turn_off_for_chromecast:
  sequence:
    - service: remote.send_command
      data:
        entity_id: remote.living_room_ac_remote

    - delay: '00:00:02'   
    - service: homeassistant.turn_off
      data:
        entity_id:      
        - media_player.bose

Now it is evening and I restarted HA.
I got the following message.

Platform error switch.broadlink - cannot import name 'NetworkTimeoutError' from 'broadlink.exceptions' (/usr/local/lib/python3.8/site-packages/broadlink/exceptions.py)

I couldn’t restart HA. I deleted the scripts, and reboot my NUC.
HA started as usual.

Is there something wrong with my scripts? How can I alter them?
