This comes in pair with the other issue 1 I opened about the OpenXR counterpart I finally managed to get some geometry rendered using the native meshing API, but I often see sporadic stacktracer in the android log.
This one shows right after a MLMeshingRequestMesh. Previous calls to the function work fine

And then when I call MLMeshingGetMeshResult after, I get this. It processed because the previous call throwing returns MLResult_Ok.
