Chris has already posted this in the Extensions section but I’m bringing it up here too to make sure it is seen by the people it affects.
In this new version (2019.2) the C++ API has been removed. If you are using certain rendering extensions in SketchUp they may not be compatible (yet) and it may be a good idea to wait to upgrade SketchUp. For more info, read Chris’ thread linked above.
If you are not using the affected extensions you are good to go. Enjoy the drag and drop importing!
