You did not say which operating system you are using. The instructions for removing anaconda3 differ by operating system. I got good instructions for removing Anaconda from the Google search engine. In a Google search panel, ask: How to remove anaconda3?
The response comes from Google’s Gemini AI system, and it works quite well. Follow the instructions for your operating system (macOS, Linux, Unix, or Windows) to remove remnants of your prior Anaconda install. Then you can install the latest Anaconda version in the standard location recommended for your operating system.
