Hi @dura3k

Have you tried going to your package manager and trying to update the packages from there?

#6

Could you try removing the current package from this folder and restart Studio and your project. It will then be downloaded again:
%userprofile%\.nuget\packages


#7

Hello and thanks
I just did - I deleted the failing packages and restarted the UIPath Studio and still the same issue

It looks like the installation might have become corrupted. Any chance you could try reinstalling the Studio. Please make sure only 1 version of the UiPath software is installed on the machine.

Also, could you copy the details of your error message by using the “Copy to Clipboard” button and paste it here?
