Finally found out what happens!
Somehow this user is forced to manual evaluation for passed modules. Training admin have a notify that he must evaluate the results, but
no items seems on the module evaluating page (items to evaluate) for the training administrator, it stucks. After deleting all unfinished attempts for this user in the "result list" making a "fresh" attempt unblocks the module.
I found it here: modules/contrib/opigno_learning_path/modules/opigno_user_selection/widget/vue/dist/userselect.umd.min.js
CFEnergizer → created an issue.

К сожалению нет, модуль так и не заработал. Просто отказался от робокассы.
