Canary 86.0.569.0 crashing on macOS Sierra 10.12

[seancorfield]

As of today's new Canary build 86.0.569.0, it crashes on launch on macOS Sierra 10.12. Removing the user library app support folder for Canary does not fix the problem. Switched to the Dev build for now.

Can confirm on macOS Mojave: 10.14.6
