Chrome unexpectedly exits after click "START AUGUMENTED REALITY"

[mohcanohca]

When starting any of the demos, Chrome Canary unexpectedly exits after click the button "START AUGUMENTED REALITY".

Device: Samsung S7 (SM-G9308)
Android version 8.0.0
Chrome Canary version 73.0.3636.2。
ARCore version 1.5.180910133
I have turned on the #webxr and #webxr-hit-test flags and nothing else.

If I removed the option environmentIntegration: true for requestSession(), Chrome will render the page without camera stream.

Any idea what causing the problem?
