Update - The error occurs on every FieldType where "use Zend\Code\Generator\ValueGenerator;" is embedded.

The Vendor directory has changed from "zendframework" to "laminas".

So I think the embedded namespaces of the "ValueGenerator" should be changed from
"use Zend\Code\Generator\ValueGenerator;"
to
"use Laminas\Code\Generator\ValueGenerator;"
on every FieldType which includes that.

Hi there,

I am on a clean install of version 9.2.0 and don't have any issues. Are there any Add-Ons you have installed, except for Block Designer which may be causing these issues? Did you try a fresh install yourself as well?

Kind regards
Ramon
