Repro steps :
- Open test project
- Open sample scene
- Drag and drop the file 33_multi.fbx into the scene view

Expected : Mesh should be imported without console errors
Result : Mesh is imported but a lot of errors are thrown into the console

I think it should at least fail gracefully and not throwing errors like this.

Addtional info :
- Happens only in an RTX project

Environment :
- Windows 10
- Unity 2020.2.0a21
- HDRP 10.0.0-preview.33
