Reproduces how often:
All the time. The browser is unusable.
Operating System and Brave Version(See the About Brave page in the main menu):
I’m not sure of my current Brave version because I can’t open it, but my last update was tonight. My OS version is Ubuntu 20.04.1
Additional Information:
The problem is simply the browser doesn’t launch with the output above.
In the meantime, you might remove Brave Nightly and then re-install. Basically the root of the problem has to do with our upgrade of Chromium 88. Some content settings were removed and we have code that handles this upgrade. Turns out there were some bugs so we backed out the bad versions and will push a new Nightly with the fix soon
