Yet very few users are suggesting any issue. I actually haven’t had any problems after updating either. So there should be another underlying issue somewhere.
Which version of Windows are you using?
Also, if you “fixed it” enough to be able to access it, think you can check for crash logs?
If you can access it and it has logs, then it would be good to create a Support Ticket at https://support.brave.com/hc/en-us/requests/new?ticket_form_id=360001330571 and advise of the information. You could also post here and see if Mattches or one of the other people from Brave swings by, but Support Ticket would at least guarantee they will see it.
