Started this conversation on a different thread this morning - re-posting here with a macos tag.
This is happening to me every time - Brave will launch and then crash immediately. I have the following Mac OS/browser configuration: Mac OS 10.15.5 (19F101). Brave Browser Version 1.10.90 Chromium: 83.0.4103.97 (Official Build) (64-bit)
I read a few posts here on the same subject and had an inkling that Rewards was the culprit.
My solution was to go into the folder
~Library/Application Support/BraveSoftware/Brave-Browser/Default/ then find the directory
/rewards_service and then I put a hash in front of the directory name and re-launched the browser from the Dock (keeping that Finder window open so I could see what was going on). I suspected the hash would force the application to generate a new directory.
Brave launched, a new rewards_service directory was created on launch and the browser didn’t crash. I then binned the hashed directory.
Caveat: I have never activated the Brave Rewards thing, I have no data stored against it so no potential loss to me.
EDIT: Just crashed again - that was only a partial success dammit. I’m re-posting this with a Mac tag to see if anyone else has an idea.
