I've found the solution.As I've told already this is related to MsDtsSrvr.dll

So, I've just Restarted the MsDtsServer110 Service.

No it works Perfectly

It's a bug in SSMS older version, and this been solved in the new versions

Please see here

The Table name will be like UserTokenCache. It will be generated by the system itself.

The columns in the table are 

UserTokenCacheId - int, not null
webUserUniqueId - nvarchar(max),null

Please remove the Connection String "column encryption setting=enabled" in our SSMS and try it again
