GUI with BrowserStack - Tunnel already opened Error

I'm using the gemini gui with BrowserStack and sometimes when I click retry for a suite it will throw an error saying the tunnel is already open (see below for full error).

Output of gemini --version:

7.4.1

Contents of .gemini.yml file:

module.exports = {
  rootUrl: 'http://localhost:6006',

Expected behaviour:

No error, it either uses the already opened tunnel or closes any previously open tunnels.
