Automation failed to run "this automation is trying to run a rule that has already started"

Hi everyone! I encounter an issue with automation. I have an automation in one of my docs which is set to run daily at (about) 12:00AM. It usually works just fine, but once in a while, it failed to run and show this error:

I don’t know what that error means, anyone can help?

FYI

  • This doc is used by about 10-15 people daily.
  • Automation is time-based daily at 12:00AM, and push a button that runs a quite heavy action (about 5 mins execution if I do it on my laptop)
  • I set “Take action as Automation Bot” on the rule
