If I look up an activity that I know should be there, then all of the activities appear, but only in that workflow, and only until I close Studio, but also this error shows up:
Downgrading my dependencies breaks the entire project, I am not sure what is causing this. The project actually works fine, it’s just that I can not see it in Studio.
What I meant is that where it says drag activity here, there supposed to be activities, this is a complete project, but it shows that Main is empty. When I run it, it runs fine, I just cant edit it since it does not show up.
After referring to the post you linked, and downgrading my UiPath.Excel.Activities to 3.0.1, my project was restored I can see everything now and the errors are gone. Thank you.
