  • Delete “UiPath folder” installation from C: drive.

Can you check if the project.json file in the folder location can be opened in a Notepad or if it got corrupted?

Yes able to open file in Notepad

This looks like an issue with the Studio as per Updating UiPath.System.Activities from 22.4.x to 22.10.x fails - #8 by alexandru

I saw you tried upgrading to new version too. Can you do Uninstall using the Control Panel > Uninstall Program and install Studio 23.4? Let me know if it works!

Still same error after Upgrade to 23.4.1

@Manish_Kukreja - Try this:
Go to C:\Users\MKukreja\.nuget\ and rename the folder named packages to packages-backup. If the operation fails, close Studio, end UiPath related tasks, and browsers and try again.

Studio will recreate this folder back when you open a solution

Thanks
