Jupyter Notebook "Run all cells" won't work + autosave not working

Hi, this is my first message here. Everytime I open a Jupyter Notebook, I have to manualy run each cell. I still have the code I wrote in the cells though.

Besides, the autosave feature does not work even though I see it checked in the Settings.
I have to manually save my notebooks.

I feel the 2 issues might be linked to cookies or cache in my browser.

Please help.

Thank you.
