Failing to load usd file


When I try to load a usd file using a python script, it returns an error and I get the following message:

2023-09-21 19:22:31 [8,187ms] [Warning] [omni.usd] Warning: in _ReportErrors at line 2830 of /buildAgent/work/ca6c508eae419cf8/USD/pxr/usd/usd/stage.cpp – Could not open asset @/home/xxx/git/RRL_pushing./assets/glovebox-simple.usd@ for reference on prim @anon:0x15450fd0:World0.usd@,@anon:0x154510d0:World0-session.usda@. (recomposing stage on stage @anon:0x15450fd0:World0.usd@ <0x15036850>)

This is a model originating from Unreal Engine and converted into usd. This model works fine on the gui version but when I try to open it with “add_reference_to_stage” on my python script, it fails.
