Não consigo executar o projeto devido a porta 8080 | Spring Boot API REST: construa uma API

Quando eu clico na opção Run As... e escolho o item 1 Java Application ele abre uma janela chamada Select Java Application onde possui um campo chamado Select type (? = any character, * = any String, TZ = TimeZone): onde possui dois asterisco e abaixo, possui uma serie de classes, uma que já vem marcada é a Attacher - net.bytebuddy.agent e que quando aperto no botão ok, ele não informa nada o console fica vazio.

Contudo, quando estou na classe main, e aperto a tecla F11 ele dá o seguinte erro:

APPLICATION FAILED TO START

Description:

Web server failed to start. Port 8080 was already in use.

Action:

Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.

Já olhei o gerenciador de tarefas do windows procurando pelo PID do processo que está usando está porta, contudo, não há nenhum programa usando a porta 8080.
