I started to have this problem after an update, and it's annoying to have to use the secondary click to show finder.

Try using command-tab to select the Finder instead.
Also note if there is a dialog box that requires attention from another application, it may stall your ability to switch to the Finder. You can also leave a window open on the Finder on the right hand/bottom part of the Dock by minimizing it with the yellow control, and then clicking on the minimized window in the dock, which appears adjacent to the trash bin.

Finder does not show when clicking on it, it only shows with secondary click by choosing "show all windows"
