Hello Lumi Support Team, I am experiencing an issue with Lumi Cloud. All H5P activities display a blank white page when I click View. This happens with: - Uploaded H5P files. - Newly created H5P activities directly in Lumi Cloud. - Single Choice Set and Multiple Choice activities. The Chrome Console shows this error: `Uncaught TypeError: Cannot read properties of undefined (reading 'Button')` The stack trace references: - H5P.Question 1.5.15 - H5P.SingleChoiceSet 1.11.88 - Question.self.addButton() - SingleChoiceSet.addButtons() The content can be opened in Edit, saved successfully, but cannot be viewed or played. Could you please investigate whether this is a Lumi Cloud H5P library or dependency loading issue? Thank you for your assistance.
