Assessment doesn't work

I am able to watch the videos for my learning path if I clear my cookies every time before I watch a video. Is this normal? Is there a way to fix this? The main issue I have is that  every time I try to do the assessment I just get the screen you see below. I have tried it in both google chrome and Microsoft Edge. Any clue how I can fix this? I need to submit that I have done the assessments but I haven't been able to do them.
