Awesome! I’m so glad adding the missing keys actually does bring it back. Out of curiosity, since this fixed you, but not another user, do you mind checking something for me?
From start if you open appwiz.cpl, does Brave show up as Installed? If so, then this may not be what caused it in the first place. If it doesn’t however, and doesn’t show up in the list, we might have found a root cause of the “effect” (just not the cause of why it’s missing).
