matlab runtime mwarray assembly failed to be initialized after running my application for multiple days

We have a C# application using matlab code compiled in a DLL. It always works, except when running the application for a long time, then close it and restart the application. The application can not load the matlab runtime at this point. It gives the following error:

Failed to start matlab runtime mwarray assembly failed to be initialized

We can only solve it by restarting the computer. Is there a way to prevent this from happening or resetting the matlab runtime without having to restart the pc?
