Migrating and Upgrading to Joomla! 4.x • Error Call to undefined method Joomla CMS Application

Hi
After upgrade to Joomla 4
When I want to edit a custom html site module, I got this error:

An error has occurred.
0 Call to undefined method Joomla\CMS\Application\AdministratorApplication::isAdmin()

If I activate error reporting, it shows me this:
