UiRobot is not a valid Win32 application

I’m getting an error message when trying to run the UiRobot.exe with a xaml

I have been using the same command previously and worked correctly. I’m not sure why I’m getting this message now.

Any ideas on how to resolve it?

can u add that xaml?

It happened with all xaml, but I managed to sort this issue by doing a repair installation.
