Exact same problem, getting a crash every 2-3 days or so on my 3 weeks old MBP 13"/16GB/256/.
Sometimes it's not the freeze, it's something different: upon opening the lid, i get a completely garbled up screen (super pixelated, greenish/grayish hue) where i can only see the mouse moving, nothing else can be observed; the mouse arrow itself is just a huge pixel, about 1 x 1 cm on screen. Shutting down is the only thing that helps.
For the freeze yesterday i managed to copy the error report: it's all about Bridge OS! See below:
{"caused_by":"macos","macos_system_state":"running","bug_type":"210","os_version ":"Bridge OS 2.4.1 (15P6805)","timestamp":"2018-09-20 14:22:40.80 +0000","incident_id":"A38855BC-160F-4170-946B-CC144FA47BDF"}
