If you are still experiencing this problem, I linked some posts from other topics with this issue that worked for those community members. I myself know nothing about macOS but hopefully these links help.
I think that you can resolve this by deleting the Brave-Browser-arm64 folder (in /Library/Application support/), then try launching the browser again.
On my side I did only this steps:
delete the Users/[your user name]/Library/Application support/BraveSoftware folder
relaunch Brave
and it worked.
I didn’t uninstall Brave, nor downloaded it from Github.
The BraveSoftware folder is recreated when Brave is started, but does not prevent Brave to start anymore.
(You may need to enable the display of the Library folder in Finder layout menu.)
Happed to me. Open terminal and type in “sudo rm -rf ~/Library/Application\ Support/BraveSoftware”
like @289wk said I recommened closing the brave browser first.
Please note, the below solution reinstalled Brave Browser from GitHub. Apparently, you do not have to do this.
The solution to this problem was exactly that, steps I took:
Downloaded the package directly from Git
Installed the Software
Went into User>Library (it’s a hidden folder)
Deleted the BraveSoftware folder
Relaunched Brave and it worked normally.
Another link in case you need.
