Visual Studio 2017 HRESULT: 0x80070005 / E_ACCESSDENIED on project creation : <p>I'm running Visual Studio 2017, version 15.0.0+26228.9</p>

<p>When I'm trying to create a new project via <em>File > New > Project...</em> in Visual Studio 2017, I'm receiving the following error message and the project is not created:</p>

<blockquote>
  <p>Access denied (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))</p>
</blockquote>

<p>Don't mind the german message text in the screenshot:

<p>This happens for every project template I use (e.g. C# WPF, VB WPF, C# Console App...).</p>

<p>If I try to create a project via the quick search box on the starting page of visual studio, VS just crashes instantly with no exception message at all:</p>

<p>Has anybody else ran into this issue and might know how to fix it?</p>
