TranslatePress SQL errors – option.php

Hello,
Since update to WordPress 5.7 and PHP 7.4.14 I encounter the same kind of error as mentioned in this thread: error linked to options.php.
I contacted my hosting company and they confirmed that database has the permission to create and change tables.

My latest error message log looks like:

1

disable_automatic_translations	Ja

Do you have any idea what could cause the problem?
I really like your plugin, as it is a very user friendly and complete tool to manager several languages!
Thank yo so much for your help.
