I answer myself. After emptying 7 tables (discourse\_reactions\_reactions, directory\_columns, external\_upload\_stubs, associated\_groups, user\_associated\_groups, group\_associated\_groups, discourse\_reactions\_reaction\_users) **the site is up and running**. I restore the last backup too!

Thank you all for your help! Have a nice weekend 🙂
