Why did Laravel routing stop working after class import?

Question

Laravel

Good afternoon. I did a project at the Laravel course, version 5.7 is used in the course, I have version 7.2, all pages loaded, routing worked. I added a view return, the storm highlighted the line with yellow, and asked me to change the type of the return value, as in the screenshot

I chose the first option from the list, and after that the routing stopped working at all, this is how the main page of the Laravel project looks

in the inspector now, you can see that it is not loading the blade view, but an empty index page, did the cancellation of actions, but nothing has changed, how to fix such a collapse?

Answer 1

This has nothing to do with the bug you "fixed" in the storm. He just said that the doc block and the actual behavior don't match. It doesn't affect work at all.
Something else was completely broken.
