Last night 2/10/2020 I received notification of a brave update. I updated to version 220.127.116.11 and my screen turned black. This morning 2/11/2020 same thing, so started looking for answers. Found black screen posts but nothing specific to this dated version. Decided to check for any windows updates and found a - 2020-01 Cumulative update for .NET framework 3.5 and 4.8 for windows 10 version 1909 for x64 (KB4534132) - I installed this update, rebooted computer and still a black screen. I uninstalled Brave version 18.104.22.168, went to company download page - https://brave.com/download/ - and reinstalled browser. Working fine now. Hope it helps someone.
