Error when opening a test report related to stateflow

I have several mldatx files which are related to previous test results. Until yesterday, I could open them quite good tho but I today I couldn't open any because I get the following error on the cmd window:

failed assertion in B:\matlab\toolbox\stateflow\src\stateflow\utils\simutils.cpp at line 261:
