The crash is occurring due to an issue with the parallel execution infrastructure in releases prior to R2020a. Starting in R2020b, "Parsim" is internally used for parallel test execution and you should be able to directly run the tests as it is in parallel in 20b without any crash from workers.

As a workaround before 20b, you can uncheck the 'Stop Simulation at Last Time Point' checkbox in the Inputs section of both the test cases. Running the test cases in parallel after making the change should work fine without any crash from the workers.
