can't reload osgserver.dll

The matlab gives an error message that it can't reload osgserver.dll, so how can I solve it?

Does your machine have OpenGL? Because in my laptop, i have Intel's integrated graphics, which doesn't support OpenGL. So I ended up switching random opengl.dll files from the internet... After replacing it with the original DLL file, MATLAB switched to software-OpenGL, which resolved the osgserver.dll errors and let me plot, etc.
