BUG REPORT: Stack Overflow Crash Opening Grasshopper Files with Missing Components

SUMMARY:
Rhino 8.25 and Rhino 9 crash with stack overflow (0xc00000fd) when opening .gh files containing components from missing plugins. Crash occurs during ExtractObject before UI is shown, making file recovery impossible.

STEPS TO REPRODUCE:

  1. Create .gh file with component from custom plugin (e.g., ManagerTest.gha)
  2. Remove plugin .gha file from Libraries folder
  3. Open .gh file in Rhino 8.25 or 9
  4. Result: Immediate crash with stack overflow

EXPECTED:

  • Show “Unrecognized Objects” dialog
  • Display placeholder objects
  • Allow file to open and components to be removed

ACTUAL:

  • Crash during ExtractObject before UI shown
  • Crash occurs even with solver disabled
  • No way to recover file

ERROR:
Exception code: 0xc00000fd (STATUS_STACK_OVERFLOW)
Occurs in GH_Archive.ExtractObject() when deserializing missing component
Component initialization code executes during deserialization, causing circular dependency

IMPACT: HIGH

  • Files become completely unusable
  • No recovery path
  • Affects Rhino 8.25 and 9
  • Data loss risk

WORKAROUNDS:

  • Opening with solver disabled: Doesn’t work (crash before solver)
  • Programmatic removal: Doesn’t work (crash before document loads)
  • Opening in older Rhino: Works but file still crashes in 8.25/9

REQUESTED FIX:

  1. Defer component initialization during ExtractObject
  2. Better error handling - catch init errors, create placeholders instead of crashing
  3. Recovery mode for problematic files
  4. Validate plugin availability before deserializing components

ENVIRONMENT:

  • Rhino: 8.25.25314.11001 (also Rhino 9)
  • OS: Windows 10.0.26200
  • .NET: 4.8

I cannot uninstall 8.25 to install 8.21. I have uninstalled 9 and 8 but I still get this:

How can I continue to work when I cannot open my file and cannot uninstall Rhino and re-install a version that worked?

@cerfdude sorry for the late response,

Did you manage to get your Rhino working again? If so, can you post your systeminfo again?

Are you using any tools for registry cleaning (e.g. CCleaner?)

Did you try a repair of Rhino rather than a reinstall?

I am not running anything and I first tried to repair but that didn’t help. As you have been communicating with Dave Kay, I took your advice and tried to roll back to the earlier version you sent through. However I cannot install after uninstalling as it shows this:

But it hasn’t unistalled as a shortcut returns this:

I cannot manually delete the directory as it says it is open in another program:

I did manage to remove all the ristry entries and then deleted the files below \Rhino 8 \system. one by one and finally got the earlier version installed. Could you have a look at this issue please?
