Can't reach my own "Costum List" overview

Hi,

It's been 2 or 3 days since I can't reach my own costum lists page anymore. I can go directly on a custom list page. But not to the one with all of my list listed. I always get the same message (picture below)

I thought it was an all member proble. But Kate can go on it and see my Lists. And I also found out that I can go on the list page of other members. I tried like 5 different people. 🥲

Edit: I can see the page if I'm not loged into my account. Once I log in, I can't 😅
