Yes … am getting for new project as well as existing project also.

any help on this much appreciated

I would strongly advise you to do a clean installation as per instructions from this post:

If you are using the Community Edition, then feel free to use redownload the latest version 2019.5 from our Cloud Platform (Resources tab) :slight_smile:

It might also be that some security software is blocking access to some crucial UiPath files.

As per instructions I have reinstalled the uipath and now it is working properly. :grinning:

Thanks all for information and time

Hi,

We had this issue before discovering that a Merge conflict had been inserted into one of our XAML files.
Just in case anyone else has this same issue.

Thanks
