Short description of error
Exporting a cell fracture animation as GLB throws an error.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Create a mesh, merge into one object.
Run create cell fracture on it (adding a force field)
Baked the animations.
Export as GLB (initially attempt to merge all animations into single animation, failed with error below)
Attempt to export GLB without merging animation, same error.
Have attached a blend file

I did a similar animation on a different mesh last week and it worked, so my assumption is this mesh is stranger or has some quirk.
