Hello,
Sometimes the tab bar in the File Manager resets. If you close the page while it is still loading all the tabs, there is a bug that causes everything to disappear at that moment.
Could there be something that overwrites data in localStorage or the cookies, causing the tabs to break?
I’m only reporting this today, but this has always happened in the File Manager. I’ve experienced this for as long as I can remember.
