Problem rendering JSF page

Question

I have a very "boring" problem, yesterday I had a system JSF working perfectly with all pages opening correctly. When I enter the system today the page is like this:

No component of Primefaces or JSF is working more. It is already the third time that this happens and so far I do not understand why. The only solution I found was to start a new project and copy everything to it, but I would like to know what this problem could be.

Web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">
    <display-name>Inventario</display-name>
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>
        *.xhtml</url-pattern>
    </servlet-mapping>
    <context-param>
        <param-name>primefaces.THEME</param-name>
        <param-value>bootstrap</param-value>
    </context-param>
</web-app>

I’m using Maven in my project, and I have all the right dependencies.
