Same message as before. Maybe it doesn't support newest Insider builds? Wierd thing is that installed apps from Store do work (Mail, Calendar, etc). The one I found crashing when launching is Facebook for example. But I can't update or download any new. Other than that, the system seems to be just fine. I did some repairs before with tweaking.com tool but that didn't help.
Also, SFCfix.txt from desktop:
