C1W2 - Problem with opening .ipynb file in LAB Assignment 1

Hello,

While completing the final part of Assignment 1 in the second week of the Fundamentals of Data Engineering course on Coursera, I encountered an issue opening the .ipynb file, which prevented me from finishing the assignment. Has anyone else encountered this problem and know a solution?

Thanks in advance,
Lazar

Perhaps filling out this form, might reset the lab entirely!
