System Information
Operating system: Ubuntu 20.04.3
Graphics card: Nvidia GeForce 1060 GTX

Blender Version
Broken: 3.0.0
Worked: 2.9.3

Short description of error
I downloaded a source blend file from Sketchfab (Link in case).
I removed all the textures and sound files and packed it into zip:
TubaGunner.zip
Exporting the provided blend file to GLTF results in Python traceback in Blender 3.0.0:

Exact steps for others to reproduce the error

Open the provided blend file
Try to export as GLTF with default params
