Bug report: Export hangs when there's animation data.

[tdw46]

Describe the bug

I have encountered several files that take well over 5 minutes to export on my machine. Regardless of addon version, blender version, OS.

To Reproduce

Steps to reproduce the behavior:

1. Download this blender file.
2. Try to export VRM of objects visible in viewport.
3. Export will take a long time
4. Notice there are 12 actions in the file
5. Delete all 12 actions and try to re-export
6. Export will be very short

Expected behavior

Export should take a short amount of time regardless of number of actions in file when exporting VRM. Should only consider actions in file if exporting VRMA.

Desktop (please complete the following information)

• OS: Windows 11
• Blender 4.2, 4.3
• Addon Version: 2.33.1
