Answer

I tried to reproduce the issue, and it fails when you run yum with python3 instead of python2:

python3 /usr/bin/yum install java-11-amazon-corretto-headless
  File "/usr/bin/yum", line 30
    except KeyboardInterrupt, e:
                            ^
SyntaxError: invalid syntax

You should use python2, not python3 for yum:

python2 /usr/bin/yum install java-11-amazon-corretto-headless

It seems that in your instance default python version was changed to python3.
