IFTTT Webhooks no longer working: Getting "already running" error message

Hi guys! I was hoping someone might be able to help me. At some point since updating I’ve found that my IFTTT webhooks are no longer doing what they’re supposed to be doing and I’m getting the following error message:

Logger: homeassistant.components.automation.strava_webhooks
Source: helpers/script.py:1122
Integration: Automation (documentation, issues)
First occurred: 5:34:13 PM (2 occurrences)
Last logged: 5:34:13 PM

Strava Webhooks: Already running

I saw this problem before and after a few restarts and an update to the latest version it seemed to be fine but now it’s showing the above error message again.

My automation to accept webhooks is below:

- alias: Strava Webhooks
  trigger:
    - platform: event
      event_type: ifttt_webhook_received
      event_data:
        action: 'call_service'
  condition:
    - condition: template
      value_template: "{{ trigger.event.data.service == 'var.set' }}"
  action:
    - service_template: '{{ trigger.event.data.service }}'
      data_template:
        entity_id: '{{ trigger.event.data.entity_id }}'
        value: '{{ trigger.event.data.value }}'

Any advice you can give on what’s going wrong would be really appreciated.
