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?

2.Check whether you are using any of the following functions in your code. These functions are not supported for compilation and might create issues after compilation. Refer to the following documentation to identify the unsupported functions:
