the plugin isn’t loading - for some reason like permissions etc (the fact chart director & valentina are also not loading leads me to suspect this is the cause)
You did quit & restart the IDE after installing the plugin ?
If it still gives you unknown type for mysqlcommunityserver then its still not loading the plugin
What I cannot diagnose from here is why
DebugView for window may be needed to see the launch log messages which may be instructive
THen you can see if the IDE is really skipping loading those plugin
Jorge - you might want to take that image down because it has your key visible. Although you whited out your key in the editor, the errors list at the bottom has the entire key displayed.

Please grab DebugView from Microsoft and start it before you start the IDE
