thanks @Gustavo

Is this a local install?
How did you upgrade?

This location. Update was done by the ubuntu manager.

Do you have the same issue when you run your older version of Kibana against the 7.10 version of Elasticsearch?

The previous version is working.

thanks for listening, but i solved the problem by deleting the * kibana indexes.
For some reason the migration was not successful, leaving indices previously created.
