Mac Book Air freezes when attaching any files
Every time I try to upload a file to a website, access a file in MS Office, or attach a file in an email my Mac Book Air freezes.
The window pops up to upload or attach the file but it will not allow me to select a file or cancel the action. The window does not have the red, yellow, and green button to close, minimize or enlarge the window.
This just started on Sunday March 28, 2021.
