Error upgrading spring boot version to 2.6.6-CodePudding

I am upgrading my spring boot application to latest stable version 2.6.6, The Build is successful, but getting below errors on runtime. How can i look why this class PropertySourceLocator is missing, and what steps can someone generally take to solve such issues related to dependencies like in my case. I have tried various things like excluding any conflicting dependencies, using compatible versions of different libraries like spring-boot and spring cloud.

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [MainApplicationClass]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/cloud/bootstrap/config/PropertySourceLocator.class] cannot be opened because it does not exist

Do you have dependency for that class?

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-context -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-context</artifactId>
    <version>3.1.0</version>
</dependency>
