I ran into the same error message when attempting to create an Amazon Linux 2 instance using the AWS CDK. The CDK currently defaults to Amazon Linux instead of Amazon Linux 2. When you accidentally use an Amazon Linux AMI from 2018, surprise surprise, all sorts of facilities are not available. I posted an easy way to check your version in another answer.
In CDK (and Cloud Formation) make sure to declare your intended generation in your AmazonLinuxImage properties

Amazon Linux 2 Python incompatibility woes
I didn’t have any issue with 3.9 and epel on al2. But I rarely use it. As someone else said pyenv or i generally take it a step further and just use docker since all of our stuff is already set up to easily run a container anywhere. I am generally so over touching python in the host os at all, or php, or really anything. Having to depend on their repos and all of that. No thanks. Take a few minutes and just forget what your host os is and containerize it where you will never again have those issues. I personally start with alpine but there are some good official and updated bases you can use to get you a full python environment on alpine in seconds. And customize anything else you need. That also makes sure if you ever change a host os that doesn’t have the same default modules installed you don’t even have to care. I would say forget packaging your software with rpm and go docker. Same concept. You publish a repo and version and all that. It just doesn’t have to care about the host os. At all (well, mostly ;)) More on reddit.com

March 16, 2023When AWS says that the Amazon Linux kernel is optimized for EC2, they're not kidding
I would not expect such a big difference across two different flavors of linux. It would be interesting to see other variables here - which version of imagemagick is being used, do they all have the same compilation flags and how do other cpu heavy tasks differ across distributions.

It looks like this issue is potentially being caused by YUM priorities. You could try disabling priorities to see if that is the issue. The config file used to disable yum priorities can be found here.
/etc/yum/pluginconf.d/priorities.conf
Change the config to be "enabled = 0" and try again.

Check the Amazon image version of your EC2 instance.
Command: cat /etc/image-id
If it is Amazon Linux 2023, it does not have extras.
However, most of the packages are already included in the distro.
You can run sudo yum install nginx which will install version 1.22
