Thanks all, it looks like this issue is directly related to what’s being reported https://github.com/brave/brave-browser/issues/58699. The team is aware of it and reviewing.
Quick update: We’ve found the likely cause and a fix is in review. We’ll update again once released. https://github.com/brave/brave-core/pull/40490
once fixed build is released what is the correct way to update my browser since i can’t launch it?
Of course … with the browser not running … (hack, sputter & cough - "and, the hand crank could not even get the old clunker running) …
On your Mac, as a precaution, go to: /Users/[YOUR_USERNAME]/Library/Application Support/BraveSoftware and back up the Brave-Browser folder.
And standby for what a member of Brave Support suggests about the installation procedure.
