TF26006: Team Foundation could not find 0

Question

We are running some issues with our TFS builds (2012 with update 3). For a team project, all builds are ending up with an error: Exception Message: TF26006: Team Foundation could not find 0. (type DeniedOrNotExistException)

Symthoms are:

• For other team projects, builds are running fine. There is a problem for all builds in a specific team project.
• Builds generate drop artifacts into folder but doesn't update test servers (that's an xcopy operation with powershell command which is triggered after build).

So far we have tried to restart our controller and agents. It didn't work out. Is there anything else we can try?

Edit: Full expection stack trace is here:

Issue was resolved once build server's Team Foundation cache is fully cleaned (You had better stop build services before, so that you won't have to deal with files which are locked). To do that, i cleaned the content of folder below: C:\Users\username(Team Explorer user name)\AppData\Local\Microsoft\Team Foundation\4.0\Cache
