How can I fix the "zsh: command not found: python" error? (macOS Monterey 12.3, Python 3.10, Atom IDE, and atom-python-run 0.9.7)

Since I got the macOS v12.3 (Monterey) update (not sure it's related though), I have been getting this error when I try to run my Python code in the terminal:

I am using Python 3.10.3, Atom IDE, and run the code in the terminal via atom-python-run package (which used to work perfectly fine). The settings for the package go like this:

The which command in the terminal returns the following (which is odd, because earlier it would return something to just which python):

I gather the error occurs because the terminal calls for python instead of python3, but I am super new to any coding and have no idea why it started now and how to fix it. Nothing of these has worked for me:

• I deleted and then reinstalled the Python interpreter from python.org.
• I tried alias python='python3' (which I saw in one of the threads here).
• I tried export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin" (which I found here).
• To reset zsh and paths, I deleted all associated hidden files in /local/users/ and ran the terminal once again.
• I deleted everything and reinstalled Mac OS X and the Python interpreter only to get the same error.
