I'm in the same boat. I use Firefox on Windows 11. The computer is an Asus TUF Gaming A17. I have also tried hard-refreshing. The box pops up randomly, sometimes not showing for hours, and then re-pops up. I even tried clicking on "click here" to fix it and it would pop up again within a few minutes. Usually it would be after I finished adding in a container box for my articles. I took a picture of the issue and added it to this post (I hope it shows up).
