Thanks for the report. I'm able to redo the crash but occasionally. Issue is probably related to threading since the crash occurs in tbb module.
(Haven't checked yet in debug build)

No problem. If you uncheck import material then it works fine by the way. Maybe suggests the material being created by the importer messes up something to do with memory when creating the new material?

I can confirm the problem.

Apparently caused by 600c069e0e.

I'm not sure if the bug is in the USD importer, Draw Manager or in the Add Material Slot operation.
