Formula pop-up missing

This afternoon when I try to open a fx formula pop up, it wont show up. I cannot find it anywhere on my screen and then the main page is not responding when I click. But there’s a message sound when I click on the page.

Can anyone help me?

It’s working now, thank you so much!
