"Location currently not available." for any new folder

[soldier9599]

Every time I create a new folder I have to restart XYplorer (which takes about a minute) because as soon as I try to navigate into that folder it says "Location currently not available."

Which OS?
Which XY version?
Which menu item/button/key shortcut?
Where (local/LAN(\\, or mapped drive))?
