APPLICATION FAILED TO START after upgrading to spring boot version 2.3.1.Release - spring

Question

I'm using spring boot 2.3.1.RELEASE, spring-cloud-services.version 2.0.0.RC2 and spring-cloud.version Hoxton.M1, and face following issue while starting application:
APPLICATION FAILED TO START
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.cloud.stream.binder.rabbit.config.RabbitServiceAutoConfiguration.configureCachingConnectionFactory(RabbitServiceAutoConfiguration.java:72)
The following method did not exist:
org.springframework.boot.autoconfigure.amqp.RabbitProperties.isPublisherConfirms()Z
The method's class, org.springframework.boot.autoconfigure.amqp.RabbitProperties, is available from the following locations:
jar:file:/home/vcap/app/BOOT-INF/lib/spring-boot-autoconfigure-2.3.1.RELEASE.jar!/org/springframework/boot/autoconfigure/amqp/RabbitProperties.class
The class hierarchy was loaded from the following locations:
org.springframework.boot.autoconfigure.amqp.RabbitProperties: file:/home/vcap/app/BOOT-INF/lib/spring-boot-autoconfigure-2.3.1.RELEASE.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.boot.autoconfigure.amqp.RabbitProperties
After upgrading to spring boot 2.3.8.RELEASE and spring cloud to Hoxton.SR9, I am getting following exception:
