here is a solution for your issue:)

It worked when I renamed my xaml file to Main.

I am not able to resolve it, it has happened on two of my PCs
My xaml file is already named main.xaml

Hi @deepak1745

I would suggest a fresh install of UiPath Studio to solve this issue. You could also try a few things to see what the cause is:

  • is it an older project that was recently opened in newest release?
  • what is the project name?
  • does the issue happen on a blank, new project?
