Where did you get this message? Python is built into macOS so there shouldn't be a separate installer.

Nope, Python 3 (although only 3.7.3) is in Catalina.

Do you have a standalone Python installation on the computer? Can you post a screen shot?

no standalone python installation, it only appeared once after the update so cannot provide screenshot, everything works fine, what issues do I look for if python crashed?

Maybe some specific app you use bundles its own copy of Python that has become messed up.

In Catalina 10.15.4, from Terminal,
python2 --version
returns Python 2.7.16
python3 --version
returns
Python 3.7.3
which python
or
python --version
tells what version is used by default.
To use python3 instead of python2, I added an alias
echo "alias python='python3'" >> ~/.zshrc

I had a problem with Python too, I ended up deleting ~/.zshrc and creating a new alias with
echo "alias python=/usr/bin/python3" >> ~/.zshrc
