As of last few hours I can no longer sign into Google account with Brave.
I can sign in with Safari.
On the first attempt sign-in page refreshes and on the second attempt the page hangs (endless loading).
I tried deleting data for the accounts.google.com to no avail.
UPDATE:
After changing User agent to Microsoft Edge (Chromium) - Mac, I am able to sign into my google account with Brave (kinda) once again. Not an ideal solution.
