Internal solver isn't always able to solve a model

The internal solver is able to solve the model sometimes, restarting the program sometimes changes this behavior. The model in question is attached. AutogeneratedtestDebuggingPhaseMostLikelyCompleted.sysdyn When the solver fails the following error is produced for each project module:
