Magento – Column not found: 1054 Unknown column ‘at_status_default.value’

I'm actually kind of desperate.

I tried many times to update my Community Edition from 2.2.1 to 2.2.5, always failing due to what I guess is a database inconsistency.
After the update procedure – done with Composer – I get this error:

{"0":"SQLSTATE[42S22]: Column not found: 1054 Unknown column 'at_status_default.value' in 'where clause', query was: SELECT DISTINCT  COUNT(DISTINCT e.entity_id) FROM `catalog_product_entity` AS `e`\n
