After deleting the cached directory also, if it does not work, look at the terminal for an error.
If he says
[ 96470] ERROR - llij.ide.plugins.PluginManager - null
Then this is a problem with some plugins that you already installed in the IDE.
In my case, it was a BlackBerry Pugin for Android development. I just removed it from the plugins and it worked.
Click the plugins in the drop-down list at the bottom right and remove the plugin that you installed manually.
