2019 TouchBar MBP 15" forced restart during video chat in Google Chrome

[mknightretke]

Dear MacRumors Community,

My brand new MBP crashed three times in a row tonight while participating in a video chat on messenger.com in Google Chrome. Each time, I was a few minutes into the chat when the machine froze (unresponsive trackpad and Touch Bar), then suddenly powered down and restarted. I didn't hear the fans spinning up. Could it be overheating?

On the third time, I got the following error report:

{"caused_by":"unknown","macos_version":"Mac OS X 10.14.6 (18G87)","os_version":"Bridge OS 3.6 (16P6568)","macos_system_state":"running","incident_id":"5F67CF05-D7F0-44F1-B697-0B3725FB969A","timestamp":"2019-08-31 02:54:03.84 +0000","bug_type":"210"}
