Problem editing H5P content after upgrade to Wordpress 7.1

Dear all,

I hope someone could help me with this.

We had several content created with H5P within Wordpress (with the H5P plugin) of different types (concretely we are working with documentation type and the branching scenario). We could edit them without no problems.

After upgrading to Wordpress 7.1 some days ago, the edition of those contents is permanently loading in each image field, dropdown menu, etc. and we cannot edit them anymore.

We have tried editing it in different web browsers (Firefox, Edge) with the same result. We are working on it on Desktop. The H5P plugin version is 1.17.

I attach an screenshot with the example of the Loading message. The problem is only when editing, not visualising the content.

Many thanks in advance for the support!
