Describe the bug

dialog "NewFolderOpen" freezes when scanning a large number of directories. There is also a slowdown even when scanning a small number of directories.

I also want to add that sometimes the folder is not displayed, it shows that it is empty until you update it.

How to reproduce

Open the folder selection window and enter a directory with a large number of directories
