ADDITIONAL INFORMATION
I came across this issue when I was trying to connect and execute tasks on a fresh AWS set-up (new S3 bucket + EC2), I'm using the latest (5.1.0) release and Ansible 5.10 (as per pip show).
The issue itself is the same as ansible-collections#637 and the last comment is the fix, there's another PR addressing this issue ansible-collections#786 but is quiet since May
Also AWS seems to be deprecating PATH addressing style: https://docs.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html#path-style-access
Thanks to timburnet-systematica and james-masson for their initial work on this.
