How I solve the Error 401 Twitter API in R?

Question

I was performing a tweet analysis using the rtweet package in R. But when downloading the tweets search_tweets() the the following error occurs:

Error: Twitter API failed [401]. Check error message at https://developer.twitter.com/en/support/twitter-api/error-troubleshooting

• Could not authenticate you. (32) In addition: Warning message: Could not authenticate you. (32)

I have already performed the authentication again with the command

auth_setup_default() 

and

 auth_as()

But the same error keeps happening
