Planner on Teams - Error adding a comment

Hi,

When using tasks by planner on Teams, i can't add coments because of this error : 

"Vous n’avez plus accès à « a1fe5143-3a11-4466-aebe-8d5eb6f8d656 ».

My colleague who is using the same tasks planner with the same Microsoft licence have no problem to do it.

How could I fix this error ?

Thank you for your help
