Release Type: Official Release/GitHub (please choose appropriate option)
I'm using the official release from the stride website

Version: Version number and/or git branch
stride 4.2 released very recently

Platform(s): Does the problem occur on Windows, Android...?
Windows

Describe the bug
the built in code editor in stride isn't able to find assemblies and modules like System or any Stride modules

To Reproduce
Steps to reproduce the behavior:

1. create a new script in stride and open it in the editor

Expected behavior
what should happen is I should be able to edit the code and get proper autocompletion like in stride 4.1 but instead it throws completely random errors, to worsen the issue it only happens in the built-in editor It seems to be perfectly fine when opened in vscode

Screenshots
Stride 4.1, everything is working the way it's supposed to:
