Steps to reproduce

1. Download the attached minimum reproduction project, extract and open in the Godot Editor.
2. Open the "Monke.glb" file from the file picker and click re-import. The editor should not crash now.
3. Click the AnimationPlayer node and play the animation present inside it.
4. Repeat step 2. Editor should now crash. If not repeat step 3 and 2 (on some very rare occasions I had it work correctly).

Did you at any point select a skeleton 3d node?

Did you at any point select a skeleton 3d node?

Not during the same session, no. The AnimationPlayer does animate on a Skeleton3D node though so if there are known issues with that it might be related.

Looks like some pointer acess violation:

Crash call stack:

Sometimes it didn't crash but the error log will spam:

Personally I think we should stop any animation playing in scene upon reimport.

I confirm the issue in 4.2 beta 6. It spams errors about p_bone out of bounds as pointed out by @jsjtxietian.

For me on Linux it doesn't lead to a crash right away, but I suppose it might eventually if the MessageQueue runs out of space.

For comparison, in 4.1.3 it also shows errors, but only once, no spam:

This still occurs in 4.3
