spring boot 2.5.6 without spring security and security config upgraded to spring boot 3 making swagger not working

When trying to upgrade my spring boot project from 2.5.6 to 3.2.5 swagger UI stops working.In version 2.5.6, I do not have spring security nor security config. I have only SwaggerConfig :

@Configurationpublic class SwaggerConfig {    @Value("${spring.application.name}")    private String applicationId;     @Value("${spring.application.description}")    private String description;     @Value("${spring.application.version}")    private String version;    @Value("${app.env}")    private String env;     @Bean    public OpenAPI openAPI() {             return new OpenAPI()                     .info(apiInfo())                   .components(new Components());    }    private Info apiInfo(){        Info info= new Info();            info.setTitle(env +" - " + applicationId);            info.setDescription(description);            info.version(version);        return info;    }}

Is it necessary to add spring security after upgrading to spring boot 3.2.5, or should i change my SwaggerConfig? Or is the problem somewhere else?

Thank you very much and have a good day.
