I think is because the project is on one drive
Try to copy paste the project folder on system somewhere in c drive
And see if u r getting the same error ?
Also open the project from project.json while accessing it do not directly open from main.xaml

Sometimes I encounter that error too.

Close the studio and Open Studio ;

Open the .json folder

@58_Talib_Qadri Is it resolved now ?

[jitendra.saroj]

Having the same issue

@UiPath_Community @uipath
If it will not resolved then i need to design again from starting.

Check the package from where it’s calling all the packages
In the settings cross check once

I was able to resolve this error after searching and finding no one else seemed to solve without rebuilding. This occurred when copying a .xml from one project to another, I updated dependencies on both projects and closed them then I copied file in question into the destination project again and it worked. They were not using different dependencies either this just somehow magically fixed.
