As a test, do any of the other items open from within the en-US folder, or is it just an issue with this specific one?
Run a SFC /SCANNOW command to see if it finds and able to repair any corrupted system files.
Afterwards, see if anything may open from the en-US folder.
Thanks for suggestions guys, I have reinstalled and eventually find out, what caused it.
It was because of disabled service: Tile Data model server, it disabled Start/Store as well.
