SCVMM console client crashing while trying to check VM template properties

Hi all

here is the situation:

• SCVMM 2012R2 UR6
• several VM templates

Whenever I try to see properties of VM template with more tan 3 disks - SCVMM clinet crashing. No issue when I want to see properties for templates with 1 or 2 disks. 

I though it might be some issue with template itself - so - I deleted template and created new one - same issue again.

I tried from different workstation, different operating systems - nothing changed.

Any thoughts ?

thanks for any hint.
