I also had an issue with Google News, clearing browsing data worked for me.
You could try clearing all browsing data of your current user profile.
brave://settings/clearBrowserData => Advanced => Time range: All time => Check all options => Clear data
Note 1: This will log you out of all websites, make sure you know your logging credentials for websites you log into!
Note 2: Clearing the browsing data for “Site and Shields Settings” resets global Shields settings. If you are not using the default global Shields settings, you’ll have to re-adjust the settings at brave://settings/shields after you clear the browsing data.
All right. Just to make sure the issue isn’t related to your current user profile, you could test Google News with a fresh user profile. Creating another user profile DOES NOT affect your current user profile in any way, don’t worry about your browsing data.
Testing with a fresh user profile is the last thing I can recommend to you at this point. Good luck.
