Quickstart files open and then close instead of running

A console opens, some text that is too quick appears and then console closes.
Any ideas on how to tackle this? Or any tips at least from which angle to look into it?

No specific file or test is named. Start by reproducing the quickstart launch and capturing the console output before it closes, then inspect the quickstart files involved in starting it; done means the quickstart runs without the console closing immediately.
