Cannot access back office : ZipSourceHandler non-existent

[BRIC2]

Hi, 
I have a very annoying problem accessing the back office of my website
When I try to access it, I get the following error :

The service "mbo.modules.source_handler.addons_url" has a dependency on a non-existent service "PrestaShop\PrestaShop\Core\Module\SourceHandler\ZipSourceHandler".

At first it was a different one : Unable to generate a URL for the named route "admin_mbo_catalog_module" as such route does not exist.
But manually deleting var/cache made it change to the new one above.

 

Does anyone know how to solve this problem? 

Thanks in advance 🙂

I found more about the issue :

It appears that disabling debug mode allows me to access my back office, but doing certain actions like saving changes sends me to an Error 500 : Internal server error page.
Enabling debug mode makes it appear again, and keeps from accessing back office

If anyone knows what might be the cause of the issue, i'd gladly hear about it !
 

Kind regards,

Disable Marketplace module either rename its folder. Test it.

I have the same error. Could you solve it?

 

Btw. Renaming ps_mbo didn't help.
