Problem with COM Interop & Windows 10 1607 (Anniversary Update)

I have an application (C#) which uses ComInterop with CorelDraw x8

After Updating to Windows 1607 (Anniversary Update), things stop working immediately with creating my object (cdr = new CorelDRAW.Application();), or with the next line (hiding CorelDraw's window) with an error:

System.Runtime.InteropServices.COMException

App busy.

(Ausnahme von HRESULT: 0x8001010A (RPC_E_SERVERCALL_RETRYLATER))

or later

HRESULT: 0x80010105 (RPC_E_SERVERFAULT)

Same app with same Version of CorelDraw x8 under Windows 7 continued working as it should, and after uninstalling Windows 10 Anniversary Update, my apps is working again as intended.

So, does anyone know how to work around this issue? Is it known yet? Any help welcome :) !
