**Release date: 8 February 2024**

## Bug fixes

* You could not remove the URL of an Automation Hub idea linked to a project.
* Studio did not indicate that validation errors could not be solved after automatic reference import in projects that contained read-only files. The Project panel now displays a message that the read-only status of project files may hinder project cleanup.
* Studio used more memory than expected after editing and closing projects in which multiple interdependent libraries were installed.
* Studio did not limit syntax validation errors to the activities that were causing the errors in some projects.

* When double-clicking to view a collapsed [CV Screen Scope](https://docs.uipath.com/activities/other/latest/ui-automation/cv-scope) activity that contained other CV activities in some Windows - Legacy projects, the ![docs image](https://dev-assets.cms.uipath.com/assets/images/studio/standalone-docs-image-plus_menu-8a20ac7d.png) icon used to open the **Add activity** search bar did not appear.

* Creating or opening a project on a machine that was not connected to the internet was slower than expected.
* Further improvements were made to a fix for project compilation failing when running a C# project that contained a library added as a dependency if the library included an activity with the **In** argument of type **Newtonsoft.Json.Linq.JObject** and the project included a variable or argument of the same type assigned to the input property of the custom activity.
* Validation errors occurred after importing missing references in some Windows C# projects if Studio's interface language was set to German.
* Compilation errors were not cleared after correcting a variable type mismatch using an [Assign](https://docs.uipath.com/activities/other/latest/workflow/assign) activity.
* Stopping the debugging process on an activity that had a breakpoint did not prevent the activity from executing.
* The **Universal search** bar displayed inconsistent search results depending on how many project files were opened.
