Viewport RigidConstraints Crashes when within WorldModel and SurfaceGui

[Seiiyo (Seii)]

In the PlayerGui, I am using a SurfaceGui to render and manipulate a Viewport Model. A WorldModel containing the model is parented to the Viewport Instance. I do not experience a crash when I select the same constraint when the model is outside the WorldModel. I am uncertain if these crashes occur in other scenarios such as ScreenGui instances.

In spite of the fact that no changes have been made, the crash occurs immediately upon selection within Explorer. This problem does not occur when the position is modified via the command line. I am able to safely make changes to properties through scripts, which is why I classified the problem as a Studio issue. I have attached a Repo file.

Thanks for the report. We’ll investigate this.

Hello! Does this crash still occur for you? I am trying to reproduce (thanks for the file!) but I can’t get studio to crash. If the crash does still occur for you, can you post detailed steps as to what you do to get it to crash?

Thanks!

Yes, the crash still is affecting studio.
These are the steps I take to replicate the crash.

1. Using the place-file supplied, I run the game with client F5
2. Once the client is running the place, navigate in the explorer > Players > LocalPlayer > PlayerGui > SurfaceGui > WorldModel > ConstraintModel > Root > Rigid Constraint.
3. Select Rigid Constraint within Explorer and the application will hang and then crash immediately 100% of the time.

Thanks! I was able to repro with these steps. We will continue to investigate and update this thread when we have a resolution.
