After the update the unit restarted and about 5 sec after boot it red screens. I put it into USB mode and see that there is an abnormally large .json (960kb vs 3kb for the other 330 actions) in /jumpLogs/summaries. Removing the abnormally large one allows it to boot normally and not freeze on the red screen. This happened to me on the previous update as well and removing that summary worked fine until this update which I assume restored it.
The offending file is s_action_559_20180714_1427-240.json
