Dear Autodesk,
We are launching the 3ds Max 2025 application via the command line and opening files using our C# library with Autodesk.Max.dll through a WebSocket connection. Although the files open as expected, when we open the Tools > Crease Explorer dialog and then close it, moving to the next file sometimes causes the file to not load properly, and the 3ds Max 2025 application crashes.

We are manually launching the 3ds Max 2025 application and attempting to open the Tools > Crease Explorer dialog. After closing it and moving to the next file, the file opens as expected.
