Reinstalled anaconda. Now my code won't execute properly

I had to make some changes to my computer (MacBook OS Ventura 13.6.9), and I found that my anaconda app wasn’t working. So I decided to delete it and then redownload it. I’ve finally managed to do so, and I’m getting errors on all my code that used to be running fine. My guess is that maybe my version of Python changed upon redownload? But I’m not sure how to check that. I think I was running Python 2.7 or 3 before. But I really don’t know where to start troubleshooting.
