Unable to create SharePoint 2013 workflow

Hi,

Whenever I try to create a SharePoint 2013 workflow, I get the following error: "Microsoft SharePoint Designer can't start Microsoft Visio. An error occurred and this feature is no longer functioning properly. Would you like to repair the feature now?"

If I select "Yes", this error keeps on flashing again and again, and I have to open the task manager to end the task.

I work on SharePoint Online. Does anyone have any idea about the error?

Thank you!

Regards,
