Hi Team, after completing the sql code and executing the cell for exercise 1, it is taking too long to complete and there is error message. Please kindly check, as I still facing this issue after attempting this lab for 3 times.

I am experiencing similar issues for the C3W3 Assignment on Advanced SQL Queries. I’ve tried it in multiple versions on three different browsers - it seems effectively unusable
