I'm on a Mac mini M1, Big Sur 11.1, Xcode 12.
I can add the USDZ file to the hierarchy with no issue, but as soon as I click it, the program crashes. Thereafter, every time I attempt to reopen the program, it immediately crashes. I have to delete the USDZ file from its location on the hard drive, and then I can open the Xcode project and delete the reference to the missing USDZ file. I've tried different USDZ files, and the exact same behavior each time. I've found a couple of vague references to this happening in conjunction with other issues, but nothing that seems to directly related to fixing this problem.
