This crash does not occur on iPhone devices. Tested on an iPhone X device.
When switching environment capture to manual for iPad, the crash did not occur.
1. Have an ipad.
2. Grab AREnvProbe from Sandbox -> AR
3. Package with default settings for iOS. (AR_session config should have Environment Capture Probe Type set to -> Automatic)
4. Install and launch app on an iPad pro.
App crashes after starting an AR session
Able to run on all devices with automatic capture
