TypeError: PDOStatement::fetchAll(): Argument #2 must be of type int, string given in PDOStatement->fetchAll() (line 2299 of /app/docroot/includes/database/database.inc).
this error is caused next code
$authorized_rids = db_select('block_role', 'br')
->fields('br', array('rid'))
->condition('module', $module, '=')
->condition('delta', $delta, '=')
->execute()
->fetchCol('rid');
fetchCol method supports only integer arguments

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I am using Drupal 7.92 and the patch "quicktabs-database-error.patch" fixed the issue for me.
LGTM. RTBC++
