Yeah this seems like a super strange issue.
@arielle0902,
If at all possible, I’d love to see a short screen recording of the behavior if you can manage it, just so I can see exactly what is going on.
We have a list of tools you can use for this on Community and you can upload anything captured to imgur.com and paste the imgur link into your reply here and it will automatically embed the video.
From what I can tell so far, it does seem, as @Saoiray suggests, like something is blocking or removing Brave from your machine. So I’m also interested in what type of anti-virus/firewall software you’re using on your machine. I would also be curious (after you share the screen recording and other possibilities are exhausted) whether or not downloading/installing from our Github would make a difference for some reason. You can find all of our releases/versions available for download there — here is the page for the latest release build:
