attach custom environment dialogue crashing

[DirtWolf]

Trying to attach a custom environment and the window auto-closes as soon as my files load. I'm just playing around right now, but, not the best.

2.0.12376
Active Plan: Fusion 360, Subscription
macOS 12.1 x86_64 (21C52) on iMac19,1

Well I turned off ground plane and it still crashed. But I discovered that if I click on a file fast enough it will actually load before the window crashes. neat-o!
