Encountered the same bug in version 7.10.4.

The underling 'exercises/#exercise_id/details' endpoint does communicate the right 'dueDate' and the frontend also displays a correct date.
The 'studentParticipation', contained in the same endpoint response, shows a 'locked' of true though.
Trying to commit results in a 403 error response.

I can not reproduce this. What is the exact actual behavior/error that you guys see @isabellagessl @LionHoltkoetter?

PS: I think I did something wrong. I deleted the whole participation instead of just the submission, sry @isabellagessl @LionHoltkoetter. Now I see the problem
