Chrome and Horizon Persona Management

Anyone running Chrome in Horizon (version 7) with persistent google profile (using persona management)? 

It requires a Google Chrome ADM, which was fine, all that worked out ok.  First day it was fine, too, albeit slow.  Since then, however, every time someone logs in, the desktop reboots without warning.  I'm having a hard time pausing the reboot so I can get in to see logs.  I've scoured the internet, too, for similar problems and nothing. 

Any wisdom someone can shed would be wholeheartedly welcome. For reference, there's pretty much nothing else on the desktop, Chrome is our primary tool.  Windows 10 LTSB, (pre-anniversary)

thanks,
