vs2015 ctp6 error at create new project

Question

I'm using Visual Studio 2015 CTP 6.
When I click New Project..., I get an error message:

"Object reference not set to an instance of an object".

Visual Studio does not crash, but the template choice dialog doesn't appear. If I reinstall (all vs2015...) the problem is solved, but only for two days or so...

I know this is beta software, but anyway I really enjoy the improvements, I would be happy if anybody has any idea why this is happening or a shorter time resolution than the overall installation.

@jessehouwing's comment it was the solution for me. I deleted the entire contents of this folder:

%AppData%..\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

(you can delete it herself). And it works great. Thanks to @jessehouwing's and all ..

TIP: for delete form PowerShell type:

Remove-Item -Recurse -Force ($env:APPDATA +  "\..\Local\Microsoft\VisualStudio\14.0\ComponentModelCache")
