Open a ghx file of a running program

Hi everyone, I met some questions in opening a ghx file.I downloaded a C# program with multiple iterations (ghx format) on GitHub.
This is not a large file, but my rhino can’t open it all the time. I think the reason is that complex iterations have started during the program loading process.
Any ideas?

Thanks :slight_smile:Test.ghx (95.1 KB)

I found that I could edit this ghx file. If it is caused by the optimization iteration during the loading process, can I avoid this problem by modifying the ghx file?
