Composer install/update inconsistant 

I'm struggling to get the recommended composer configuration running. Just some times, if I execute an update or install command, I get the following message:

The service "mautic.dynamicContent.subscriber" has a dependency on a non-existent service "mautic.focus.helper.token".

IMO this is somehow related to autoloading. Can someone confirm that or tell me what I'm doing wrong?
