Attachments
Based on my testing, when a USD file has a sublayer that points to an empty USD file, a crash occurs.

this is a first file - test.usda

#usda 1.0
(
    defaultPrim = "set"
    subLayers = [
        @./empty.usda@
    ]
)

def "set" (
)
{
}

this is a second file - empty.usda

#usda 1.0

and this is maya crash log

hi @yujiecong thanks for logging this issue. I believe this is something we have already fixed on mayaUSD 0.24.0, we had a similar issue logged internally and worked on. are you able to update your plugin to 0.24.0 and give this workflow another try?

I have tried it on my side, and couldn't reproduce this crash on 0.24.0.

cheers!
