SSRS Reports - Visual Studio 2013 crashes when I add or refresh datasources

I've Visual Studio Premium 2013 Update 4. I use Visual Studio to edit SSRS Reports(Microsoft Dynamics AX -> Report Model) for Microsoft Dynamics AX 2012 R3.

When I add a datasource to my report, that I choose for the propertie "Data source Type" the value "Report Data Provider" and then, when I click on 'Query' propertie to choose the table, I've the following message :

When I go to the event viewer, I just have the following error message without other precisions :

Can you help me please ?

Try setting following ENV variable :

1)Open your System Properties. (Right-click start menu, select System, then Advanced System Settings)

2) Click the Advanced tab
3) Click the Environment Variables button

4) Under the System Variables block, add the following value:
       a.  Variable name = COMPLUS_LoaderOptimization
       b.  Variable value = 1

5) Once the value has been loaded, restart the AOS service.
6) Close any instances of Visual Studio, re-open and attempt building another AX project or report.
