I have a Google Colab notebook which was working properly before but now it does not respond at all. When I execute a cell containing a simple python Hello World program, the cell starts to run but does not give any response. Even I cannot interrupt the execution.
When I open this notebook in an incognito tab, it works. I tried with clearing browser cache but it did not work.
My other notebooks work without any problem.
I am using Google Chrome browser.
