got the same problem, closed the reality capture, opened it again, but not on stem, then program told that there are something wrong with license or steam, closed. Opened RC via steam and got the same error message error unexpected program state failed to load project node/RealityCapture “hack” do not helps lost 6h clicking control points ;/ so it would be great that there would be possibility to import all that metadata, sfm files to new projects. Also from now I will save two copies the same project.
