When the Find All window is opened, it flashes white and just shows an empty gray box.
The content might be off-screen, but I couldn’t find a way to move to window and the only way to close it is with Alt+F4.

Edit: Nvm I fixed it
Please describe how you fixed it then mark your reply as the solution, so anyone else encountering the issue knows how to resolve it.
Ive had this issue myself for a while. It’s not blank actually, it’s the area that’ll be filled with search results once you type something. I grabbed the side of the window and widened it and that seemed to pop it out of its position somehow.
