I use m1 MacBook Air, a couple of days ago l upgrade my Mac os with latest version.  
subsequently reinstalled the anaconda navigator.

After reinstallation, when I run the Jupyter note, the terminal comes and shows the message like below, and it is all. Jupyter does’t works.

In addition, Spyder neither works.

I try to run the Spyder (ver 5.1.3), pop up comes with error message

I upgraded higher version but same error happen.

How can I fix these problems??

Now, they are working.

Time solves the troubles.
