Bug Report: tyFlow v2.100 Free Version Shape Operator Crashes 3ds Max 2026 On Click

[307896794]

Hello tyFlow Development Team,
I am a licensed tyFlow user and I am reporting a critical, reproducible crash bug.
Version information: tyFlow version: v2.100 3ds Max version: 3ds Max 2026 GPU: RTX 4060Ti 8GB Graphics Driver: NVIDIA Studio Driver
Bug description: Whether I work in an existing scene with geometry, OR a brand-new blank empty scene with NO objects at all in the viewport, adding and enabling the Shape operator inside a tyFlow event will immediately trigger an Application Error and force 3ds Max 2026 to close/crash.
This crash is 100% reproducible. It is not an intermittent error caused by scene geometry, collision meshes or resource overload. I have already troubleshooted my workstation environment thoroughly: removed redundant CUDA developer packages, clean-reinstalled NVIDIA Studio graphics drivers, tested multiple brand-new empty Max files, and the crash still happens consistently.
The Shape operator is essential for my workflow of cloth simulation, sheet/paper dynamics and mechanical particle animation. This bug completely blocks my production work, I cannot continue my projects when this operator crashes the host application.
Screenshot is attached: it shows the crash popup window, tyFlow editor UI and the application error message.
Could you please investigate the Shape operator code in this release as soon as possible? Please let me know the progress of the fix, or any temporary workaround if available.
Thank you for your support.
Best regards, Date: 2026-10-21

Please download the latest build (v2.101) and see if it still happens.

I followed your recommendation and downloaded tyFlow version 2.101 for testing.
I completely cleaned up the old tyFlow installation before installing this new version.
The crash issue persists even in a brand-new empty 3ds Max 2026 scene with no extra geometry or modifiers.
I can reliably reproduce the crash in two ways:

- Right-click any operator inside the tyFlow Editor panel
- Use the Tab shortcut to add a Shape operator
Either action triggers the 3ds Max Application Error dialog and terminates 3ds Max.
Could you please investigate this problem? Thank you.

I can't reproduce the issue here and I would expect a huge number of other reports of this issue if it was indeed caused by something as simple as right-clicking on an operator or adding a Shape operator (and I've received none)...so the fact that you're experiencing it is quite mysterious...
