13.3.1 keeps freezing internet access for several apps
Since upgrading to 13.3.1, the following happens several times a day (sometimes more than once per hour):
-Many apps can’t connect to the internet, including Safari, TV, and Chrome.
-Firefox, however, can connect to the internet.
-When I open a message in Mail, even one that’s stored locally, the message appears blank.
-I can’t close Mail messages.
-I can’t open the Trash in Finder (I get the spinning pinwheel cursor).
-Other oddities.
Usually it resolves itself after a few minutes.
I have restarted many times and it still happens.
