Strange, when I start Grasshopper in debug mode from VS (testing my component) I get the following error message when trying to save the GH definition, but it works if I start the GH definition in a normal Rhino session (no debugging involved).
If I try save to .ghx it saves without problem.
Has anyone else encountered this problem?
Rhino Version 6 SR13 (6.13.19058.371, 02/27/2019)

(Bump). Is there anything I can do to track down the cause of this error?
Again, I can save ghx, but not the binary .gh version of the gh file. Does this perhaps indicate some serialization problem. If so, can I trap that error myself somehow?

So the second error is when you try to load that file which didn’t save correctly?
No, it’s the report (messages, see screenshot) from the one and only error I get when trying to save the gh version (edit:) when started from VS for debugging:
Edit: Hm, interesting. if I first save in ghx format and after that save in gh format, then it saves!

Just to be clear: although there’s a workaround as mentioned above (first saving to ghx, then to .gh) the original problem remains in that the gh file cannot be saved without the workaround.
