Thanks for your support.
Unfortunately, still not possible to open Brave. I tried for my Mac Os with Brave-Browser-arm64.pkg and Brave-Browser-arm64.dmg as well… but always the same error response…
Please find report attached if it can helps.
That helped me. After installing I had to delete this BraveSoftware folder which is a hidden Folder. In the marked Thread you can see how to make that folder visible for deleting.
