Outlook workflow not triggering

I built this workflow to categorize my emails and send notification for important emails. when I test, it works smoothly, but it took very long time to toggle to active. now even though its active but it’s not triggering, and whenever i made some change, changes cant be saved, it shows connection lost error.
but my other workflows has no such issue.

Please share your workflow
