There is some issue in rebuilding schema for multilingual instance when upgraded to 5.x version. For the moment you will need to manually rebuild the schema using drush or civi api.
Details to rebuild schema can be found at Multilingual instances show 'no such field' errors after update
this might be specific to this one site, but in case it's not here's what worked for me. after any upgrade to civicrm for a multilingual site, after the civicrm database upgrade, run
drush php-eval 'civicrm_initialize(); CRM_Core_I18n_Schema::rebuildMultilingualSchema(["en_US","es_MX"], NULL);'
replacing the language codes with whichever languages you are using
