I've upgraded from v1.37b to 1.38b and I am getting the following build failure in the processing queue. It happens for one project in the solution. There are no dependencies on this project, but the build processing stops completely after this error. I've tried deleting the NCrunch cache, disabling and re-enabling NCrunch, but the issue persists.
