Since it complains about line 135, it has the new application class already at the point of update and therefor backporting to 21 should be enough:
https://github.com/nextcloud/spreed/blob/stable20.1/lib/AppInfo/Application.php#L133
https://github.com/nextcloud/spreed/blob/stable21/lib/AppInfo/Application.php#L135
