Course Builder Error after latest update

Hi Tutor LMS Support Team,

After the latest update, I am encountering an error when opening the Course Builder in the backend.

The editor fails to load and displays the error: “Oops! Something went wrong” along with the advice to clear cache and check plugin versions.

Key details:

• Behavior: Pressing Ctrl + F5 temporarily resolves the issue, but as soon as the page is reloaded or reopened, the error reappears.
