Have similar issue

realize the problem been in my Pom file

I added 2 dependencies together while I MUST to use only one of them

        <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-web</artifactId>
           <version>5.3.20</version>
        </dependency>

or

        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
