Hi AngilynK,

Thank you for trying those steps.

What happens when you attempt to delete the file? Do you get a specific error message?

Are there any updates for the macOS that need to be installed? If an update is necessary it can cause unexpected issues such as this one.

1. From the Apple menu  in the corner of your screen:

Choose System Settings. Then click General in the sidebar, and Software Update on the right.

Or choose System Preferences. Then click Software Update.

2. If Software Update finds new software, click the Update Now or Upgrade Now button to install it.

Enter your administrator password, if asked. During installation, your Mac might restart, and you might see a progress bar or blank screen several times.
