I can't get Designer to work

I am doing the 14 day trial of Designer. I use Vaadin 19.0.2 with Java 11 (but or also tried other versions of Vaadin with the same result). I followed the tutorial https://vaadin.com/learn/tutorials/vaadin-designer-tutorial . I got to the point where it says “Adding the components”. Chrome opens regularly but I can’t drag & drop the components to the Paper. Chrome refuses to take them and the Paper stays blank.

Hello Dario, do you have all project dependencies installed in your node_modules folder? Could you try to remove this folder and execute mvn afterwards?

I use the Node which is automatically installed by Vaadin 14.2 and above. I did it all again on another computer but with the same result, Designer doesn’t work
