I have a file I’ve been working on without problems for the last few days. About an hour ago, the file crashed (page stopped responding) without any code running. I have tried closing and restarting Jupyter Notebooks multiple times and whenever I try to open the file, the page loads the top Jupyter menu ribbon and then stops responding. Nothing changes in Jupyter’s command line window either. I can open other notebook files perfectly fine, just not this file. Nothing changed in the folder in terms of files other than an irrelevant excel file that is not named anything significant to the file that isn’t working (no overlapping import names, etc.). Any help on what could be causing this?
