a file that doesn’t exist

Hi josephdevincenti,

Is this a file you recall having previously? If so, check and empty your Trash to ensure it isn't in there.

• Delete files and folders on Mac - Apple Support

"Empty the Trash

1. On your Mac, click the Trash icon in the Dock.
2. In the window that appears, do one of the following:

• Empty one item from the Trash: Control-click the item you want to delete, then choose Delete Immediately.
  • In the warning message that appears, click Delete.
• Empty all of the Trash: Click the Empty button in the upper-right corner of the Finder window. You can also click the Finder icon  in the Dock, then choose Finder > Empty Trash.
  • In the warning message that appears, click Empty Trash.

Items that you move to the Trash from your Mac remain until you empty the Trash. You can choose to automatically empty the Trash in Finder preferences.

Items that you move to the Trash from iCloud Drive are automatically emptied from the Trash after 30 days, regardless of Finder preferences. You can choose to empty the Trash sooner than 30 days.

WARNING: Any items emptied from the Trash are no longer available."

Also, check what is sent to start when you login to your Mac. Go to System Preferences > Users & Groups then select "Login Items" from the tabs in the middle. If that file is there, select it and then the minus "-" button to remove it.

Cheers!
