Tutorial - Build Main View - "Please wait, loading view ..."

Hi, I need your help.
I tried https://vaadin.com/docs/latest/tools/designer/getting-started/setting-up-your-environment
I have a 14 day trail version. I can see the username and proKey in the proKey file.
When the main-view.ts was created, the following message appeared in the viewport: “Please wait, loading view …”.
Later I have added the first elements. But it takes a long time to wait for each element (Like waiting for a timeout).
There was nothing shown in the preview. Only a white window.
Have I forgotten something?
I had also tried to change to chrome. But it also does not work.
