### Reproduction steps

- Clean Jenkins install v2.319
- Using AWS Credentials Plugins v1.32
- Assigned IAM Role for Jenkins master instance (AWS EC2) to be able to get information for a AWS ECS Cluster (ListContainerInstances and DescribeContainerInstances)
- Install Amazon Elastic Container Service (ECS) / Fargate (https://plugins.jenkins.io/amazon-ecs/) v1.24
- Go to Manage Jenkins -> Configure System -> Configure Clouds -> Click on Add a new cloud

### Results

Expected result:

Able to see the list of ECS Cluster resources based on the IAM Role granted to Jenkins master server.

Actual result:
- Cannot retrieve the expected ECS Cluster Resources
- The small window inside show errors *A Problem occurred while processing the request*

- Checking the Jenkins System Logs, in turns out there was an issue with ```java.lang.LinkageError: loader constraint violation: loader (instance of jenkins/util/AntClassLoader) previously initiated loading for a different type with name "com/amazonaws/ClientConfiguration"```. Please refer to log
[aws-cloudbess-error.log](https://github.com/jenkinsci/aws-credentials-plugin/files/7487651/aws-cloudbess-error.log)

*Note*
Downgrade AWS Credentials Plugins to v1.30, it works properly and can retrieve the expected ECS Cluster Resources

Reproduce the issue with AWS Credentials 1.32, Amazon ECS 1.24, and the Jenkins EC2 IAM role described in the report. Start with the attached system log and the Configure System cloud setup, then investigate the reported ClientConfiguration LinkageError. Done means Jenkins can list the ECS cluster resources without the processing error.
