Simulator freezes when running detox tests #1526

We're having an issue when running our e2e test suite, particularly when running on CI (Bitrise).
During the test suite, a few tests (different on each run) will error out with:

  ● Test suite failed to run

    Timeout - Async callback was not invoked within the 120000ms timeout specified by jest.setTimeout.Error: Timeout - Async callback was not invoked within the 120000ms timeout specified by jest.setTimeout.

      at mapper (node_modules/jest-jasmine2/build/queueRunner.js:25:45)

What actually happens is the simulator freezes and becomes unresponsive (it's impossible to click on anything, use the keyboard, turn it off using the rendered power button; you need to kill it using Cmd+W, or restart using Hardware menu). When it happens, all following tests in the given file fail with a Timeout error.
Then, when we're starting a new test suite (new spec file), a new simulator is opened by Detox and the tests carry on... until this happens again.
I've seen it happens 2 times in the test suite, resulting in 3 simulators being open (2 of them frozen).

Error log for the test suite in which this happens:

I.e. logs for frozen tests testing deep links (using either device.opernURL() or device.launchApp()):

Any hints on how to resolve this?

It makes it impossible for us to run our tests on CI, as this happens at least 50% of the time.

ReactNative version: 0.59.9 (same thing occurs on 57.6 though)
Xcode version: 10.1
Detox version: 12.11.3
Applesimutils: 0.6.7 (same thing happens on 0.6.6, 0.7)
