Has Office been updated yet for Joomla 3.8.10 / 11
Helix has a bug which was fixed in the latest version but Office seems to still running the older Helix version.
So when you upgrade, you can no longer view or edit menu items in the Administration system.

A quick fix is simply to add the following after line 136


JForm::addFormPath(JPATH_PLUGINS . '/system/officehelix3/params');
// Helix fix for Joomla 3.8.10
if (is_object($data)) {
$data = (array)$data;
}
// End Fix


However, i'm sure we would all prefer an official Stackideas fix/update for this
