visual studio 2013 crashes when opening a file

Question

I could work without any problem in my C# projects. Today suddenly all attempts to open a file within VS cause an error (total crash, VS tries to find a solution, restart of VS, problem still there). The loading of the solution seems to be OK...

I did a lot of research but could not find a solution yet. What I tried is:

• System reboot (of course ;-) )
• Check for Updates (running Win10, everything up to date)
• Create a brand new project (same error)
• Try different file types (xml, cs, dataset, ... same error)
• read ActivityLog.xml (found errors concerning EditorPackages)

This is the most telling entry in ActivityLog:

  <entry>
    <record>593</record>
    <time>2015/11/03 20:34:29.514</time>
    <type>Error</type>
    <source>VisualStudio</source>
    <description>SetSite failed for package [Microsoft.VisualStudio.Editor.Implementation.EditorPackage]</description>
    <guid>{E269B994-EF71-4CE0-8BCD-581C217372E8}</guid>
    <hr>80070057 - E_INVALIDARG</hr>
    <errorinfo>No EditorOptionDefinition export found for the given option name: Graphics/Simple/Enable
Parameter name: optionId</errorinfo>
  </entry>

Some people suggested to delete or rename a folder named ComponentModelCache but I cannot find such a folder (if I'm not wrong it should be in the same folder as the ActivityLog).

So it has to do with the EditorPackage (seems to be obvious as I get the error when trying to edit a file...)

Please show me a way to repair my VS! Thx!
