Fails (access to procected memory) with special blender file

[newcode3000]

I have installed the binary open3mod_1_1_setup.exe from http://www.open3mod.com/

The attached maze.zip contains the file maze.blend (for blender 2.8) and the file maze.glb ,
that was created from maze.blend by exporting it with the File / Export / glTF 2.0 (.glb / .gltf)
menu command.

When I drag the .blend file into the program, the following message occurs:
"Sorry, this scene failed to load. What the importer said went wrong:
Es wurde versucht, im geschützten Speicher zu lesen oder zu schreiben.
Dies ist häufig ein Hinweis darauf, dass anderer Speicher beschädigt ist.
(in English: Attempted to access protected memory. This is often a hint that
other memory is damaged).

Similarly, the file maze.glb fails to load with the following error message:
"Sorry, this scene failed to load. What the importer said went wrong:
failed to read file: maze.glb (error importing file: OBJ: vertex index out of range)
