How to start local server with symfony 5 or downgrade version to 4.4?

I started a new project in new Symfony 5 and i can't open my local server.

On Symfony 4.4 the command PHP bin/console server:run is OK,

But with Symfony 5 the command appears not to be defined...

C:\Users\Chris\Code\api-test> php bin/console server:runCommand "server:run" is not defined.Do you want to run "server:dump" instead?  (yes/no) [no]:

So how to downgrade or start the local server?
