Course 3 Week 2 Practice Lab 2 gets stuck at 50% when loading jupyter notebook

Hi, I’m trying to access to the last practice lab of week 2 and the lab won’t open. I investigated and I thought it was a problem with Coursera itself, but I can access to other labs, for some reason this one won’t load. So now I’m stuck and I can not finish this week. I even tried incognito.

I started watching next week’s videos though.
