The error is caused due to call of axes after setting the 'defaultAxesLineStyleOrder' to -|-|-.
This issue is fixed from 2019b.
As a workaround if you are using release earlier R2019b you may use below command
set(0,'defaultAxesColorOrder',[0 0 1],'defaultAxesLineStyleOrder','-');
Also, in the question mentioned above, you wanted to create m-subplot but in the code your are not plotting m-subplot this may affect the result.
