Correct the classpath of your application so that it contains a single, compatible version of org.axonframework.eventsourcing.eventstore.jpa

Here is the issue:

    <dependency>
        <groupId>org.axonframework</groupId>
        <artifactId>axon-spring-boot-starter</artifactId>
        <version>3.0-RC1</version>
    </dependency>

should be:

    <dependency>
        <groupId>org.axonframework</groupId>
        <artifactId>axon-spring-boot-starter</artifactId>
        <version>3.4</version>
    </dependency>

since you upgraded the axon library to v3.4.
