Cypress crashes when using Cypress Dashboard for parallelization

[ddzz]

Current behavior

I'm trying to use Cypress Dashboard to run a test suite in parallel. When I run Cypress 6.7.1 using cypress run --config-file config/cypress.json --record --key <KEY> (without the --parallel flag), roughly two thirds of my run before I see the following error. I see the same error with the --parallel flag.

I'm seeing the same error on three different environments: locally with macOS 10.15.7, CircleCI with Docker, and a Jenkins build that runs with Docker.

The Test Runner unexpectedly exited via a exit event with signal SIGSEGV

I did not have this issue when using the Cypress Dashboard a few months ago with the same test suite using Cypress 4.8.0.

Desired behavior

Tests pass without failures.

Test code to reproduce

Our repo is open-source and available at https://github.com/department-of-veterans-affairs/vets-website. Cypress tests are named *.cypress.spec.js.
