EnvironmentLocationNotFound when click the conda button

The error reports, when I click the conda tab button in the browser. The info like that:

Error

---

An error occurred while retrieving installed packages.
`EnvironmentLocationNotFound: Not a conda environment: /Users/username/anaconda3/envs/anaconda3`

In the reality, I don’t create the env about anaconda3. And I find that there is not anaconda3 directory in the directory /Users/username/anaconda3/envs/

The version of Jupyter

The version is 4.4.0
