The method Drupal\Core\Database\Database::convertDbUrlToConnectionInfo() in that there is the possibility the array key $query['module'] is not set. Only in D10 all database drivers live in a module, therefor it must be set. Also the connection class Drupal\\Driver\\Database\\{$driver}\\Connection no longer exists.
Remove and refactor the code of the method Drupal\Core\Database\Database::convertDbUrlToConnectionInfo().

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I think this is outdated now - the method was alteady cleaned up and latest approach IIUC is to default anyway the module name to be equal to the druver name if not specified.
When the module is not set in the connection array, Drupal will use the database driver name as the module name. Therefor we can mark this issue as outdated.
