It seems that this problem is happening because MATLAB is trying to use the Maple symbolic engine to perform the calculations. You can refer to answer and comments on this question to see how to activate Mupad or uninstall Maple symbolic engine: https://www.mathworks.com/matlabcentral/answers/276932-how-to-change-symbolic-solver-from-maple-to-matlab.
