Store crashes when selecting a package

I just bought some Coins for the Minecraft Store wihtout any issues.

But when I select a package to buy, the whole game crashes. I can browse hte store normally, but if I coose any package, it just crashes. Any help would be appreciated. So far reinstalling didn't help, logging in and out of my XBOX-Account didn't help, syncing time manually didn't help...

The only error I get is in the Event-Log from Windows. No other indicators so far for an an error. The file I attached is the one from the event log. No Idea if this is helpful or not.
