Hello @Sergio_Monge ,

This is happening for all the projects?
Or for a specific one or for only the new ones?

In this specific one, did you tried to delete the project.json file? When you start Main.xaml it will be recreated.

A comment from this forum was like:
" This error is occurs because of your NuGet.Config file is corrupted.
Solution : Replace NuGet.Config file from another working studio PC
. file Location - C:\Users\user name \AppData\Roaming\NuGet\NuGet.Config"

Also, if you use the enterprise version, you can open a ticket with UiPath Support team.

I hope it helps.

Vasile.
