Cannot set unknow member


I’ve got project on computer. It was some kind of problem with it and UiPath created copy of main file. SO i had two files


I deleted MainState file from Uipath Project tab and right now I’ve got error like this on screen.
Is there any option to recover this file (it dosen’t show in bin). I also tried to delete whole packages and install them again but it changed nothing.

Hi @Alko

Some users fixed it by rebuilding the faulty workflow file:

You can also try upgrading/downgrading activity packages.
