Hi Samuel, Thank you for your reply! I tried your suggestion and I was still running into the same problem. However, I tried installing some other packages on top of what you suggested, which seemed to do the trick. These packages are idle39 <https://cygwin.com/packages/summary/idle39.html>, python39-debuginfo <https://cygwin.com/packages/summary/python39-debuginfo.html>, python39-devel <https://cygwin.com/packages/summary/python39-devel.html>, python39-test <https://cygwin.com/packages/summary/python39-test.html>, and python39-tkinter <https://cygwin.com/packages/summary/python39-tkinter.html>. I'm not really sure why this worked, but nonetheless SageMath is now up and running! I'm now going to figure out how to run it on Jupyter Notebooks. I used SathMath 9.5.rc1 by the way.
