A dynamo file opens as a blank

I use Dynamo program in Civil3D, but recently one of my dyn data doesn’t open. When I try to open the file, a “Home” window opens without any error masseges. What should I do? Any idea?

I had that from saving a revit 2021 script in revit 2022. Opening in revit 2021 would then make it blank

Seen this too. I think it has to do with c3d 2023 dynamo scripts being opened in older versions. At least thats my experience.
