Jupyter notebook in PyCharm. Notebook kernel doesnt match project interpreter

Question

Jupyter notebook in PyCharm. Notebook kernel doesnt match project interpreter

Outputs the error " Notebook kernel doesn't match project interpreter and doesn't execute cells, doesn't even display them in the preview. Moreover, the server starts and everything works fine in the browser.

When you click "Register project interpreter as kernel", it returns an error

The project interpreter and the Jupiter interpreter are the same

What's the matter?
