AWS doesn't start (Generative AI with Large Language Models)

Week 2,
Lab 2 Fine-tune a generative AI model for dialogue summarization
When I clicked the ‘start’ button, the start lab icon was spinning and AWS color stayed yellow.

It seems like my lab needs to be refreshed. Can you help on this?

How long did you wait while the icon was spinning?

I waited one hour, then I tried it the next day, but the same.

Hopefully a mentor for this course will give some guidance here.
