La barre d'édition ne se charge

Hello,

The edit bar does not load when creating a new activity. Course presentation. Wordpress is in version 6.6.1 and h5p 1.15.8 php in 8.3
all activities work in consultation mode.
We can no longer create new activities: Course presentation and Drag and drop, we can not modify the old ones, remains in loading state and never displays the toolbar.
But the old ones still work in user mode. The other activities seem to work normally in edition or consultation.

Can you help me?

Thank you

Sincerely
