RankMath problems after last update

Hi,
I just notice that when you open an article or page in WP panel you see the rankmath section but you cannot open it or modify. It seems blocked:

The system also alerts me with this plugin error:

Today I activated Weglot but I deactivated it as soon I saw the error and the problem persists so I think the problem was born after the last rankmath update.

Please let me know!
Thank you
Marco
