My metro apps are crashing. What do I do?

[Windows Central Question]

Hello,

I have the following problem since a week. When I want to open a metro app ( wheather, news, sport,Groove and even Store app) it will appear for 1 sec. and then dissapear. The only apps that are working are mail and calender. I'm using Win10 build 10565. No other problems whatsoever. Can someone please help me?

Thanks in advance
