Expected result:
Browser would launch

Reproduces how often:
Seems to be every time.

Operating System and Brave Version(See the About Brave page in the main menu):
macOS Mojave 10.14.6 - I’m not sure what the beta version/build is as I don’t get that far

Additional Information:

Hi @Padishah,

Thanks for reporting this.

Has it successfully started up at all? Curious what Beta version # it is.

Trying to reproduce on my end but it’s loading normally.

The beta does not start at all. The only version I can see is in the stack trace. I assume it is Version: 76.0.68.116 (68.116) from there. I downloaded from the reference URL this AM trying to help diagnose a different problem if that helps with the version. I didn’t see a reference to the current download version/build on the site though.

I tried with the dev build as well and that crashes on startup for me
