Spring Boot 2.7.x and Vaadin 23.x migration to Spring Boot 3.3.1 and Vaadin 24.4.4

After migrating to spring boot 3.3.1 and vaadin 24.4.4, in the login page the login form is not showing, is this issue related to the spring security or vaadin ? I used the custom security implementation not extended VaadinWebSecurity.

Without knowing your configuration it’s really hard to help here.
