SCCM 2012 R2 SP1Site version: 5.00.8239.1000

I try to deploy Windows 8.1 to Hyper-V's virtual machine for testing.
I create very simple task:

Externally, where are no error during deployment usually, packages and applications install successfully.
But in smsts.log I always find the error:

pISoftwareExecutionRequestMgr->ReleaseRequest(ActiveRequestGUID), HRESULT=80004005 (e:\nts_sccm_release\sms\client\tasksequence\tsmanager\tsmanagerutils.cpp,136)

I don't understand, what is a source of this error. 
This error appears always.
There is smsts.log (https://drive.google.com/file/d/0BxUjLu_eglNCYXRIOUVBTE1tYzg/view?usp=sharing)
