To Reproduce

Steps to reproduce the behavior:

Try to export as VRM
Error will be thrown and VRM export will be cancelled
See error

Desktop (please complete the following information)

OS: Windows 11
Blender 4.2.2 LTS
Addon Version 2.20.88

Additional context

I don't think this issue was happening for me with the same addon version and blender 4.2 before... However, it also affects other people I work with in latest blender and latest addon version. Uninstalling blender and reinstalling doesn't fix. It looks like the io-scene gltf 2 addon is experiencing issues. But I don't think that should have changed in b4.2.2 ...

Thank you for your report!

This is a bug in the glTF 2.0 add-on that occurred when “Remove Armature Object” was enabled. I reproduced the file you uploaded. Could you please report this bug to the glTF 2.0 add-on?

To avoid the bug, the option will be disabled in the next release.
