Hi @michael.haertling

Check the below thread,

Creating first project getting Value cannot be null. (Parameter 'referencedAssemblies')

@tschmied Looks like the dependencies are not loaded properly Please try to rename the folder in this location so that they are downloaded again…if the issue persists then would recommend to reinstall C:\users\<username>\.nuget\packages Rename the packages folder Cheers

Hope it helps!!

@michael.haertling,

Can you try reinstalling the StudioX?

Thanks,
Ashok

No, this didn’t solve the issue (nether renaming the folder nor reinstalling) I used setup file available on UiPath homepage.
