ARkit unity project, video playback stops. iOS 11.2.5 with error: Domain=com.apple.arkit.error Code=102 “Required sensor failed.”

Question

camera playback stops after a few seconds of scanning, but other things(like touches) is alright. It starts after device update to 11.2.5 (we think so). In xcode I found this exception:

Answer 1

通过从Unity AR Alignment Gravity更改为Unity AR Alignment Gravity，然后在Unity Editor中的ARCameraManager上更改Start Alignment来解决此问题。
