Empty Specs List

[roypearce]

Some devs on my team are encountering an empty specs list while trying to run component tests. When inspecting the page, the specs list is just an empty div. This is preventing them from running component tests at all in the browser. Headless works fine, E2E in the browser lists the specs no problem. This issue is happening across the last 3 major versions of Cypress and with different NodeJS versions in different repos. Occasionally they can work around it by installing a new Cypress version, or removing the Cypress Cache and re-installing, or rebooting, but it quickly stops working. It happens across different browsers as well with Cypress - Chrome/Electron/Firefox.

The common denominator is that they are using Nix for system configuration, while I am not, and I don't have issues. The CLI and console don't report anything different for them than they do for me.

I know it's not a lot to go on, but it's a very odd issue without many tells, so I'm hoping someone has experienced this and knows a fix or can point me in the right direction.
