Mouse right click does not work in Editor

Hi guys, 

i updated my PHPStorm to version 2020.1 (Build #PS-201.6668.153, Windows 10)

When I try to open the context menu with right mouse click in the editor window, nothing happens. I already discovered an exception in idea.log file, every time I try to right click.
