unity-test-runner: The test runner gets stuck in the "Testing in playmode" phase

Bug description

The test runner gets stuck in the “Testing in playmode” phase. I have tried ubuntu-latest and windows-2022 docker images.

CI configuration is almost the same as described in https://game.ci/docs/github/getting-started

I used secret var ACTIONS_STEP_DEBUG = true for enabling verbose logs.

Where could be the problem?
