Package Caliburn.Micro not find

Hello, I recently downloaded and ran UiPathStudioOnPremTrial.msi to install Studio with Robot. After the install, when I open the project.json of UiPath_REFrameWork in Studio, there is a series of error messages:

NU1101: Unable to find package Caliburn.Micro. No packages exist with this id in source(s): AcmeLibrary.1.0.9, AcmeLibraryRW1.01, C:\Program Files (x86)\UiPath\Studio.\Packages, C:\Users\Wang\Documents\UiPath\RPA DEVELOPER FOUNDATION\Project Organization\ACME Activities (Library)\ACME Activities (Library), C:\Users\Wang\Documents\UiPath\RPA DEVELOPER FOUNDATION\Project Organization\AcmeLibraryRW1.01, Connect,,, Local, Official

And when I open the Main.xaml, I get the following error:

Error System.TypeLoadException: Impossible de charger le type ‘YesNoAuto’ à partir de l’assembly ‘UiPath.Vision.Core, Version=, Culture=neutral, PublicKeyToken=null’.

What should I do ?
By the way, Should I take UiPathStudioCloudTrial.msi instead of UiPathStudioOnPremTrial.msi if I want to use Orchestrator? Or should I download and use UiPathStudioSetup.exe (so older than .msi file) ?
