Error updating templates - The request timed out.

The automatic download is still giving error today, so I finally updated it by hand with no problem. Thanks.
However, after upgrading, Joomla 4.1.5 pre-check still reports failure to check compatibility of template and SP page builder and sp page builder pro and tells me that upgrading sp cookie consent is required (although I understand that the latter is simply to remove and reinstall when switching to Joomla 4.1.5)
Is there something else I need to update that I'm not seeing?

It's ok?

Thanks for your prompt response.

I have followed your recommendations and finally uploaded to joomla 4.1.5.
The back-end works correctly but not the web.
I have the error "Cannot access protected property Joomla\CMS\Menu\MenuItem::$params"
I have read in your forum that it happens because the template is not updated to Joomla 4, but I am using FLOOX and FIXTER both in version 2.0.0 updated to Joomla 4.
any suggestion?

I saw that there was the update to the new version of Helix and I assumed that I was trying to solve my problem. I've installed it and now I can't see the backend either.
I just see:

An error has occurred
0 Class 'ComposerAutoloaderInit03de505cc53b36971260b46d9d0f25c6' not found

I can't even go back anymore, please help

The hosting is Microsoft Azure and in 1 minute they have referred me to a new installation or a backup restore that I cannot do.

It seems that the problem comes from a joomla update that, I understand, should not offer me "Installer - Install from Web" https://appscdn.joomla.org/webapps/jedapps/webinstaller.xml

I have rolled back that install and see that the Helix update makes the template work except for:

On the backend:

• In the left side menu, under "Help" a drop-down with the name "SP Page Builder" is shown in blue or red that does not show anything (and I imagine it should not be here). I don't see how to send you a screenshot that would be clearer.

On the front end:

• Slideshow (full width) does not work. It doesn't show anything. I have tried several of its functions in case I detect the incompatibility but nothing works.
• Off Canvas Menu: The dropdown doesn't work. Submenus cannot be accessed.
• The Off Canvas menu and the Mega menu are shown in all views (Desktop, tablet and mobile) even if you hide it in some of them.
  Thanks for your help
