This file results in incorrect USDZ export in like 50% of cases, the result is non-deterministic.
PosedTetrahedron.zip
In half the tries the resulting mesh is missing faces:
When actually it's a (folded) tetrahedron:
Independent of whether the export succeeds or not, there's multiple logs in the console:
2x USD: Failed decomposing transform 2. The source transform may be singular.
Since the input file is a GLB you can import it with glTFast (either from OpenUPM or from the Unity registry as com.unity.cloud.gltfast).
