Relational database course with Docker, "Nothing noteworthy in there. You can't see what's in the here anymore, list the contents again." after some inactivity

I run it successfully, till I switched windows, and it looks as if it lost its track…

stuck. “Run” button doesn’t work - " tests should pass ". Reset button should reset the progress.

Is this by design? I only switched windows for a few minutes.

I clicked “Reset” button, as I wasn’t that far in, and still stuck at that same point, it didn’t reset back to start.

Even if reopening - anything typed into the a terminal doesn’t connect to the tests…

They set it up on Ubuntu, which given my experience - is a bad distro for those things - it’s too bloated… too resource consuming-wasting…
