Hello Jo,
That's because you need to add a line called “APP_KEY” and then save the changes of the .env then run 

php artisan key:generate

you will find value added to “APP_KEY”, then clear the application cache using

php artisan optimize


php artisan config:cache

Now run the server using php artisan serve and it will work fine
