Error: 0 Classe "Joomla\CMS\HTML\Helpers\Sidebar" not found

I'm working on, but the process to make it compatible with Joomla 5 and Joomla 3 is time consuming
I will let you know

I have released the version 3.3.3 to fix it

Good morning,

I updated Accordeon Menu CK to version 3.3.3 (the latest available anyway), but there is still a problem! When I go to:

Components > Accordeon Menu CK > Modules

And I click on one of the modules I created, it gives me the following error:

0 Class "Joomla\CMS\Form\Field\ListField" not found

Waiting for a solution,

Greetings
Mimmo

please enable the debug in your website to give the full error path

the 3.3.3 version shall fix it

Good evening,

version 3.3.3 fixes these errors:

when I go to the joomla components menu and select "Accordeon Menu ck", I get the following error:
0 Class "Joomla\CMS\HTML\Helpers\Sidebar" not found
Also, if I try to create a new joomla menu item, I get the following error:
0 Class "Joomla\CMS\Form\Field\HiddenField" not found

BUT IT DOES NOT SOLVE this NEW ERROR:

When I go to:

Components > Accordeon CK Menu > Modules

and I click on one of the modules I created, it gives me the following error:

0 Class "Joomla\CMS\Form\Field\ListField" not found
